First:
Disable bugeater!
Get the error messages without lua error suppressing addons.
Else Bugeater might suppress an error.

And in the error message you see the addon causing it at the bottom:
AutoInvite

Disable it and try if it solves your error messages.
If not check the next messages that occur for other addon names.
And so on.

Often there are libraries in the subfolder of older addons.
Remove them so that they won't load anymore and install these libraries via Minion/manually from esoui once to your addons folder, so you got the newest versions installed.
