In TB 60 ESR I have a bunch of accounts. In the Unified Folders I tried to deselect Local Folders' trash. I unchecked the check-mark and clicked OK. Nothing happened.

In the error console I see:
TypeError: folder is null [Learn More] virtualFolderListEdit.js:99:63

I tried a trash folder of some other account and the same happens.

Works OK for Inbox and Drafts. I haven't tried Templates, Sent and Archives.

Aceman, can you take a look.

Oh, it worked after a restart. I didn't give the full STR. First I deleted a local folder, so that moved to Local Folders/Trash. Then I emptied the that trash. Funnily, it jumped to the top. I wanted to deselect it and ran into that error. All became good after a restart. So it looks like emptying the trash is related.
