    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 IStringLocalizer by the default resource type.

    You can try:

    Configure<AbpLocalizationOptions>(options =>
    {
        options.DefaultResourceType = typeof(MyProjectNameResource);
    }

    I place the code in ConfigureServices and PreConfigureServices.

    Configure&lt;AbpLocalizationOptions&gt;(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.

    Hi,

    Ok, maybe something wrong.

    Can you provide the full steps that I can reproduce the problem? thanks.

    PS: I don't have a database from two years ago
