Second that! I’m working on a new site that using v5 and now I’m stuck cause of this bug.
Have the same exact problem.
Hi, new code fixes the problem… My custom role had the depreciated user_level capability missing. $role->add_cap( ‘level_1’ ); fixed the problem.
However I noticed that with the new code, WYSIWYG fields in both front-end and back-end show as empty. The field is being saved but the WYSIWYG field is being rendered as empty.
Thanks!
I also have the same problem, uploaded the new code but still getting an error on upload.
