I disabled all of the plugins and thought it was W3 Total Cache at first, but then I ended up with other errors.

I disabled all caching and it was still broken. I addressed each problem individually, and after a few hours of trying different things, I changed

memory_limit = 62M      ;

to

memory_limit = 128M      ;

in php.ini in my root folder and re-enabled the W3 Total Caching. That seemed to fix the problem.

Resolved!

Thanks for your help!
