Provide us with the following info:
We have 2 new problems after the 7.2 to 8.1.3 update.
The Permission page loads very slowly. When you want to give permission to the user, the save button works very very slowly. The process may take a few minutes. There is nothing missing in localization.
The second problem is that we will just start using the chat module. When we give permission to the user for the chat module, we receive an http 400 error when logged in with that user.
After upgrading from version 7.2 to version 8.1.3, I started receiving the following error in the RenderIntoBatch function.
Exception thrown: 'System.NullReferenceException' in Volo.Abp.AspNetCore.Components.Web.LeptonXTheme.dll Object reference not set to an instance of an object.
Can you help urgently?
