Are you using the default theme? If it’s a custom, you need to upgrade it. Or maybe you use default has edited templates. If that’s the case, you will have to restore these templates.
If you’re interested in display all non Editor fields in a tab, I can send a message. The Editor ones will keep having its own tab. You would still need the organizer plugin to see the order you want.
ALL profile fields or the “Editor” type ones? Regular profile fields (not Editor tab) doesn’t show up in tabs; they show up in profile sidebar, at the left side. If it’s an Editor field, like About Me, this will do the job:
Probably it’s enough to truncate the following tables should be enough:
truncate table core_search_index_tags;
truncate table core_tags;
truncate table core_tags_cache;
truncate table core_tags_perms;
I would test it on test install first or take a backup from the DB just in case.
Btw, the following queries should be executed in your SQL Toolbox or PHPMyAdmin. Then after run the support tool to rebuild your cache.
In the app install it should have copied the plugin settings, added it to the app settings and then uninstalled the plugin. For some reason which I have no idea only talking to you here, it didn’t do it. If you then uninstalled the plugin and have it now as app then it seems ok to me.
