Can't update templates.

Everything has been working fine for 4-5 days until this morning. Now, when I try to save a template, the manager window just loads a blank page and the template doesn’t save. No 404 error, just a blank page. I thought it might be similar to the error in this topic: http://modxcms.com/forums/index.php?topic=41282.0 But I talked to support and they said the only thing showing up in their logs was something snippet.reflect.php

I changed a lot in the 2-3 days since I’ve tried to modify a template so there are any number of things that could have caused it. I tried upgrading to Revolution and it didn’t work so I completely deleted my site and database and restored to the original working version of everything.

Try clearing the cache first. Something might have been corrupted there.
