Hi,
Change the database connection strong to my current running database which created by 2 year ago and working well after I upgrade to ABP 7.1.1
I think the main problem may be caused by the database, can you share the DB file to reproduce the problem? shiwei.liang@volosoft.com

I have checked the source code of ABP Framework. Volo.Abp.FeatureManagement Volo.Abp.FeatureManagement.Blazor /Components/FeatureManagementModal.razor line 65.
I past the code as below
<SelectItem Value="@item.Value"> @CreateStringLocalizer(item.DisplayText.ResourceName).GetString(item.DisplayText.Name) </SelectItem>Sometimes, CreateStringLocalizer(item.DisplayText.ResourceName) return a null object. So, GetString will throw exception.
You may think these senarios: Such as I change the file name /class name of Resource file. But a feature setting has already been stored into database many months ago...

Hi,
ABP will try to create
IStringLocalizerby the default resource type.
You can try:
Configure<AbpLocalizationOptions>(options => { options.DefaultResourceType = typeof(MyProjectNameResource); } -

I place the code in ConfigureServices and PreConfigureServices.
Configure<AbpLocalizationOptions>(options => { options.DefaultResourceType = typeof(BlazorOneResource); });But I still get the same error as before.

At first, I placed the code in PreConfigureServices. Failed as before. Then, I placed the code in ConfigureServices, Failed again.
