Not loading edit pages in admin using classic editor

Hi there. I have clean project, no any problems. But when i activate Classic Editor Plugin edit pages in admin are not working more. No errors in logs, just loooong loading with no results.
Maybe someone had this problem :slight_smile:

I can’t reproduce with the latest WordPress, Sage, Acorn, and Classic Editor plugin

What does “clean project” mean? Please provide more details

ah, sorry, i’'m stupid! 'v imported old db with 1 000 000 users that ruins users metabox (role issues big request)

have nice weekend, thanks :smiley:
