In ABP, when a feature (such as Identity.MaxUserCount) is set at the edition level, it cannot be overridden at the tenant level for tenants assigned to that edition. This is by design and confirmed in the referenced post.
To allow a higher user count for a specific tenant, the recommended and supported approach is to create a new edition with the desired feature value and assign this edition to the tenant. This way, you can customize the feature for that tenant without affecting others.
If the edition selection is disabled in the UI due to an active subscription, directly changing the edition in the database is not recommended. Doing so can lead to inconsistencies, especially with the SaaS module's subscription and renewal logic, which expects the edition and subscription data to be in sync. Manual changes may break renewal, billing, or feature assignment processes.
The best practice is to use the official APIs or UI to manage editions and subscriptions. If you need to change the edition for a tenant with an active subscription, consider:
Direct database manipulation is not supported and may cause unexpected issues with the SaaS module.

Example:
public override async Task<ListResultDto<string>> GetTwoFactorProvidersAsync()
{
// Only return TOTP provider
return new ListResultDto<string>(new List<string> { "Authenticator" });
}
Make sure your UI only displays the TOTP option and does not require email or phone verification for enabling TOTP.
You may need to customize the authentication flow in your Angular app to handle this redirect. Typically, after login, if the backend indicates that 2FA is required (e.g., via a specific response or claim), perform a client-side redirect:
// Pseudocode for Angular
if (userRequires2FA) {
this.router.navigate(['/account/manage']);
}
Ensure your backend enforces 2FA when required and that the Angular app checks for this state after authentication.

The error TypeError: Cannot read properties of undefined (reading 'component') in the SaaS Tenants page is typically caused by a problem in the Angular extensible table component, often due to a missing or misconfigured template, or an unexpected data structure returned from the backend.
This can happen if the tenant data returned from the backend is missing expected fields, or if a custom column/component is referenced in the table configuration but not properly registered or implemented.
To resolve:
If you are using the commercial SaaS module, refer to the official documentation for the correct structure and customization points:
If the issue persists after these checks, review the browser network tab to inspect the actual data returned from the API and compare it with the expected structure.

The issue you are experiencing is due to the email confirmation and reset password links being generated with the wrong base URL (e.g., https://authserver.cloverleafcms.us instead of the required tenant-specific subdomain like https://auth.homefree.cloverleafcms.us). This causes the tenant resolver to fail, resulting in a 404 error because the user cannot be found in the wrong tenant context.
To resolve this, you need to ensure that the URLs generated for email confirmation and password reset are tenant-aware and use the correct subdomain format that your HostTenantResolveContributor expects.
Configure AppUrlOptions for Tenant-Aware URLs
In your AuthServer module (typically in AuthServerHostModule), configure the AppUrlOptions to generate tenant-specific URLs for account actions:
Configure<AppUrlOptions>(options =>
{
options.Applications["MVC"].RootUrl = configuration["App:SelfUrl"];
options.Applications["MVC"].Urls[AccountUrlNames.EmailConfirmation] = "Account/EmailConfirmation";
options.Applications["MVC"].Urls[AccountUrlNames.PasswordReset] = "Account/ResetPassword";
});
Set the Correct RootUrl Pattern
In your appsettings.json for the AuthServer, set the SelfUrl to use a pattern that includes the tenant prefix, for example:
"App": {
"SelfUrl": "https://auth.{0}.cloverleafcms.us"
}
This allows ABP to replace {0} with the actual tenant name when generating URLs.
Update Email Link Generation
ABP uses the AppUrlProvider to generate URLs for email confirmation and password reset. By configuring the SelfUrl as above, the generated links will use the correct tenant subdomain.
Ensure Tenant Resolution from Subdomain
Your HostTenantResolveContributor and GetPrefixFromHost logic should already extract the tenant from the subdomain (e.g., auth.homefree.cloverleafcms.us → homefree). Make sure this logic is consistent and that the generated links match the expected format.
Database Client Configuration
If you are using IdentityServer, ensure that the RootUrl for your client in the database also uses the {0} pattern:
"RootUrl": "https://auth.{0}.cloverleafcms.us"
This ensures that redirect URIs and CORS origins are tenant-aware.
"App:SelfUrl": "https://auth.{0}.cloverleafcms.us" in your AuthServer's configuration.AppUrlOptions for account actions.AppUrlProvider to generate links.This will ensure that email confirmation and password reset links are generated with the correct tenant-specific subdomain, allowing your tenant resolver to work and preventing 404 errors.
This approach aligns with common ABP conventions for multi-tenant subdomain setups in microservice solutions.

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.
