I'm getting a really weird error.
My entire blog works perfectly, except for the post-new.php page (Posts -> Add New).
I have debugging turned on via the config file but nothing shows in the debug.log or error_log files regarding post-new.php.
It simply re-directs to /500.shtml
Just to see what was up, I made a backup of post-new.php and just put "Hello world" in the file. It still goes straight to /500.shtml. So clearly it's not even getting to post-new.php
Btw, my blog was working perfectly yesterday but I had gone over my host's resource limit and initially even /wp-login was showing 500.shtml, but slowly the site came back online, but post-new is still not working.
Thanks for the help!
