CMS Made Simple Forums

After some troubleshooting and an extensive Google search, I've yet to figure out my problem.

I'm running version 2.1.2. All I'm getting is a blank page after logging into the admin section. If I switch on debug mode, the admin console sidebar shows up but nothing appears in the central content area. Debug mode shows not obvious errors nor do my server error logs. I reinstalled the entire filesystem and nothing changed. The front end works fine with no errors. This leads me to believe that there is some sort of database setting that is wrong but I'm at a loss to what it could be.

Any help would be appreciated.

I did some more digging.

It looks like the page is getting cut off right at the point where the main content would go:
Nothing is served to the browser after that. Again, I check my error logs and don't see any PHP errors related to this.

I finally figured out the root of the problem:

If File Manager is in "Advanced Mode", the file drop zone that's in the upper right hand part of the template, for some reason, crashes the entire template. Once I removed the code for the drop zone from the OneEleven template, everything came back. Note that this does not throw a PHP error that I can find in my logs and does not replicate on my local dev server, just on my live server. Could this because there are other, non-CMSMS directories that are located in the same main directory as CMSMS? Not sure but it's definitely a bug.
