[tc4me]

PHP 7.4 currently. It was throwing missing function errors in some of the files without any obvious cause (there is no evidence of any actual missing functions). I assume it was either conflicting with another namespace in another DVZ plugin or some PHP extension was missing.

Was a very weird issue. I would have looked into it more had MentionMe not worked instead, but the other plugin seems to be working fine. Has autocomplete built-in too, which is a plus.

I'm afraid if my web space provider forces me to switch to PHP8, Mybb itself runs under php8 but many plugins are no longer maintained or adapted to php8
