XF 2.2 XF2.1 to 2.2 upgrade - Page does not refresh when submitting a PM and sometimes a regular post

[CZ Eddie]

I did an upgrade from Xenforo 2.1.2 to 2.2.16 RC2.
And now when someone sends or responds to a Private Message, the page does not refresh.
And once in awhile, the same thing happens with regular forum posts. But mostly it's PM's.
It remains on the page where you just typed your message.
So, it looks like the message didn't go through and users will keep hitting "submit" over and over.
But in reality, the message went through fine. So, we're getting duplicates.

I've made sure to CHMOD 755 the data and internal_data folders.

I do see this error.
And I should note that email (postfix+G-Suite) is no longer working as well.

Did some sort of SQL tables magic and it's somehow working again.
I'm not entirely sure exactly what did the trick though.
It was a culmination of like 30 different things.

It was definitely mail-related somehow though.
Mail still isn't working but at least I'm no longer getting mail errors.
That coincided with pages suddenly refreshing again.
