Has anyone experienced this before? I'm running MyBB 1.8.22 and using PHP version 7.3.33. These errors are showing up again and again and again. I'm at a loss as to what might be causing this. PHP version perhaps?

1.8.22 was released in December 2019, PHP 7.3 was released only a few days before, so there may have been some compatibility issues still. You’re significantly behind on MyBB versions so you urgently need to upgrade.

Thanks Matt -- I was thinking that might be the case. Do you happen to recall which version of MyBB was the last version without the drag-and-drop uploader for attachments? I'm going through the notes (and will continue searching, no worries if you don't remember off-hand) -- need to avoid that particular upgrade until I undo/modify a few template changes.
