RTFM 2.1.21 error - Revisited

Hey Everyone,
I’m encountering the 'Can’t locate object method “new” via package
"RT::FM::ArticleCollection" ’ error in RTFM, that causes the blank
output on web pages. I’ve seen the error referenced in the list
archives, but I haven’t been able to locate the fix. I’m running RT
3.4.5 and RTFM 2.2.orc2.

Here are examples from the lists:

Anyone have a fix for this?

Thanks,
Dyl
