Hi folks--
While editing in the Menus area, out of nowhere I received a 500 Internal Server Error. This error disappeared in the morning.
When checking the logs, I found many errors related to ufdbGuard.cgi
When I asked my host (bluehost) what was up, they prefaced by saying it was against policy to run proxy servers on their servers. After some searching, it seems as though some element of Squid is used in Drupal, for caching purposes (?)
1. Is this integral to drupal?
2. Does Squid come with drupal? Is it inside of Apache?
3. Any idea how to fix this? Is there some sort of restarting that needs to happen in reaction to this error?
Thanks for your help!
-Steve

new error from same action
from error logs:
Premature end of script headers: /home/chiefcit/public_html/reach/index.php
Not very descriptive. I have also setup php.ini according to the recommendations from other threads.
There seems to be some indication that the version of php can cause these problems. Any thoughts on this?
