I feel like I've exhausted my resources in trying to figure this one out. 

The front end website seems to be ok. The backend is blank except for the black navbar and the sidebar.

I've done all the restarting, dependency installs, create/remove new dbs, install blog/website, things that I've read in other posts. I'm at a total loss as to where to go next or how to debug this. This is the error in my logfile:
