This question may be related to a resolved thread.
I can’t believe it, but this is happening again, on another installation at the same hosting company. I set all the permissions correctly as far as I can tell and now even update.php is coming up blank. This is the reply I got from the hosting company support:
I’m sorry but I can not see why this error would be coming up. It is throwing a 200 ok response:
jmiller@employee-terminal:~$ curl—head http://www.lisadearaujo.com/vonnie/dashboard/update.php
HTTP/1.1 200 OK

Also, I am not seeing any errors pertaining to this in your error_logs. I would recommend contacting support forums for this specific script for this issue.
Any new ideas?
