To disable autocomplete for the password field on the ABP login page in an MVC Core Razor application, you need to set the autocomplete="off" attribute on the password input in your custom Login.cshtml file.
Example:
<input asp-for="LoginInput.Password" class="form-control" autocomplete="off" />
If you are customizing the login page, copy the original Login.cshtml from the ABP Account module into your project (as described in the ABP documentation), then add the autocomplete="off" attribute to the password input.
This will instruct browsers not to autofill the password field.

The error you are encountering when running abp get-source Volo.Abp.LeptonXTheme is a known issue that has occurred intermittently for some users, especially with certain versions of the ABP CLI and Studio. This is not related to your environment, but rather to the ABP source code server or the specific module/version availability.
The correct command to download the LeptonXTheme source code is:
abp get-source Volo.Abp.LeptonXTheme
(Do not use .Pro at the end; the correct module name is Volo.Abp.LeptonXTheme.)
If you receive an internal error or exception, it is usually a temporary server-side issue. In recent cases, the ABP team has resolved such issues quickly after being notified.
As a workaround, you can try specifying a previous version (e.g., --version 4.2.1) if you do not require the absolute latest, or retry the command after some time.
If you are still unable to download the source code, you should open a support ticket with Volosoft, as this may require intervention on their end to resolve the backend issue.
Downloading via ABP Suite is an alternative, but if Suite is also failing with "An internal error occurred during your request!", it confirms a backend/server-side problem.
You do not need to request a zip file by email; once the backend issue is resolved, the CLI command will work as expected.
For reference and updates, see:
If you need to override the Account template urgently, you may use the files from a previous version if available, or monitor the support thread for updates on the fix.

In the default ABP templates, only host users (administrators) can create new tenants. Regular users are not allowed to self-register or create their own tenants out-of-the-box. This is by design for security and management reasons.
For SaaS scenarios where users should be able to create their own tenants (self-service tenant registration), you need to implement a custom registration flow. This typically involves:
This feature is not provided by default, but ABP's modular architecture allows you to extend the system to support self-service tenant creation.

To achieve a layout in LeptonX Angular where the main navigation menu is on the left and the toolbar is at the top (similar to the old Lepton theme), this is not currently supported purely by configuration. The LeptonX theme provides two main layout options out of the box:
There is no built-in configuration to mix these layouts (navigation left, toolbar top) as you described. This has been confirmed in official support responses: users wanting this layout must implement a custom layout component and use Angular's component replacement system.
If you want to hide or minimize the toolbar, you can customize or replace the toolbar component using ABP's component replacement feature. This allows you to either hide, minimize, or redesign the toolbar as needed.
For more information on customizing or replacing components in ABP Angular UI, refer to the official documentation below.

<ng-template #loading>
<div class="custom-table-spinner">
<!-- Your spinner here -->
</div>
</ng-template>
</abp-extensible-table>
.custom-table-spinner {
position: absolute;
top: 50%;
left: 50%;
transform: translate(-50%, -50%);
z-index: 10;
}

fetchData() {
this.isLoading = true;
this.list.hookToQuery(...).subscribe(result => {
this.items = result.items;
this.totalCount = result.totalCount;
this.isLoading = false;
});
}
totalCount to 0 and only update it when the backend returns a valid number.totalCount = 0;
fetchData() {
this.isLoading = true;
this.list.hookToQuery(...).subscribe(result => {
this.items = result.items;
this.totalCount = result.totalCount ?? 0;
this.isLoading = false;
});

In a layered (multi-tier) ABP solution, email sending (including SendGrid or SMTP) must be configured in the correct layer—typically in the Web or HttpApi.Host project, not just in the Application or Domain layer. This is because background jobs or email services may run in different processes or containers, and each must have access to the correct configuration.
Ensure that your email settings (such as SendGrid API key, SMTP host, port, username, and password) are present in the appsettings.json of the deployed Web/Host project, and not only in the shared or application layer. In Azure, also check that these settings are present in the App Service Configuration (Application settings) if you override them there.
If you use background jobs for email sending, verify that the Background Worker or Job Host also has the correct configuration.
For SendGrid, if you are using the ABP Emailing system, you may need to implement a custom IEmailSender or use MailKit as described in the documentation. Make sure the dependency injection is set up in the correct module (usually in the Web/Host module).
Double-check that the correct settings provider is used and that the settings are not being overridden or missed due to the layered deployment.
Review logs in the deployed environment for any exceptions or configuration errors related to email sending.

To disable auditing in ABP Framework, you should use the [DisableAuditing] attribute on your class, method, or property. This attribute prevents audit logs from being recorded for the decorated element.
If you have applied [DisableAuditing] but still see audit logs being recorded, ensure the following:
AbpAuditingOptions.AlwaysLogSelectors or similar configuration that forces auditing.AbpAuditingOptions.IgnoredTypes (which disables auditing, but if not set, auditing may still occur).Example usage:
[DisableAuditing]
public class MyEntity : Entity<Guid>
{
public string Name { get; set; }
public string Email { get; set; }
public string Password { get; set; }
}
[Audited]
public class MyUser : Entity<Guid>
{
public string Name { get; set; }
public string Email { get; set; }
[DisableAuditing] // This property will not be audited
public string Password { get; set; }
}
[DisableAuditing]
public class MyUser : Entity<Guid>
{
[Audited] // Only this property will be audited
public string Name { get; set; }
public string Email { get; set; }
public string Password { get; set; }
}
If you have confirmed all the above and auditing is still not disabled, check for custom audit log contributors or overridden auditing stores in your solution that may bypass the attribute.
For more details, see the official documentation.

The error IDX10204: Unable to validate issuer. validationParameters.ValidIssuer is null or whitespace AND validationParameters.ValidIssuers is null or empty. means your API container cannot validate the issuer of the JWT token because the issuer in the token does not match the expected value, or the expected issuer is not configured.
In your docker-compose, you have:
OpenIddict__Validation__Issuer=https://localhost:44317/OpenIddict__Validation__MetadataAddress=http://visaflowapp-authserver:8080/.well-known/openid-configurationAuthServer__Authority=https://localhost:44317/Common Issues and Solutions:
Issuer Mismatch:
OpenIddict__Validation__Issuer and the issuer property in the discovery document (/.well-known/openid-configuration).localhost inside a container is not the same as localhost on your host. The API container will try to reach https://localhost:44317/ and fail, because that points to itself, not the AuthServer.Correct Issuer and Metadata Address:
OpenIddict__Validation__Issuer=http://visaflowapp-authserver:8080/OpenIddict__Validation__MetadataAddress=http://visaflowapp-authserver:8080/.well-known/openid-configurationApp__SelfUrl and AuthServer__Authority are also set to http://visaflowapp-authserver:8080 (for internal Docker network).HTTPS/HTTP Consistency:
AuthServer__RequireHttpsMetadata=false and ensure all URLs (issuer, authority, metadata) use HTTP, not HTTPS, inside Docker.SetIssuer in Code:
PreConfigure<OpenIddictServerBuilder>(builder =>
{
builder.SetIssuer(new Uri(configuration["AuthServer:Authority"]!));
});
Example Docker Compose Internal Configuration:
environment:
- App__SelfUrl=http://visaflowapp-authserver:8080
- AuthServer__Authority=http://visaflowapp-authserver:8080
- AuthServer__RequireHttpsMetadata=false
- OpenIddict__Validation__Issuer=http://visaflowapp-authserver:8080/
- OpenIddict__Validation__MetadataAddress=http://visaflowapp-authserver:8080/.well-known/openid-configuration
Summary of Steps:
RequireHttpsMetadata=false for internal Docker use.References:
After making these changes, restart your containers. This should resolve the issuer validation error and allow authentication to work in Docker Compose.

To allow your backend to accept requests from a locally running Blazor WebAssembly app while your services are deployed (e.g., on Kubernetes), you need to ensure proper CORS configuration in your microservice solution. In ABP 9.2.3, the CORS configuration approach remains similar, but you should also be aware of the X-Frame-Options header, which is set by default for security reasons.
Here’s how to configure your environment for local Blazor development with minimal impact:
"App": {
"CorsOrigins": "https://localhost:44346,https://your-staging-domain.com"
}
OnApplicationInitialization method, ensure:app.UseCors();
This should be before app.UseAuthentication() and app.UseAuthorization().
Refused to display ... in a frame because it set 'X-Frame-Options' to 'SAMEORIGIN') is due to the default security headers. If you are embedding the AuthServer in an iframe (e.g., for login), you need to adjust the frame options. In your AuthServer, you can override the default header:app.Use(async (context, next) =>
{
context.Response.Headers.Remove("X-Frame-Options");
// Or set to allow from your localhost
// context.Response.Headers["X-Frame-Options"] = "ALLOW-FROM https://localhost:44346";
await next();
});
Environment-Specific Configuration:
Use environment variables or environment-specific appsettings (e.g., appsettings.Development.json) to include localhost only in development.
Restart Services: After updating the configuration, restart your backend services to apply the changes.
Browser Cache: Clear your browser cache or use an incognito window to avoid cached CORS or header responses.
This setup allows you to run your Blazor WebAssembly app locally and connect to your remote backend securely and conveniently.
