Wait! Before reinstalling (unless you think you should and start fresh with less Java and junk
)
If you create a simple file called whatever.php and put one line:
<?php phpinfo(); ?>
Call that file directly and see what you get. I'll bet we see something added to PHP that is conflicting. Also run through the site and check for any blank pages that were working before. A good test is if you gave rights to post comments or anything else as anonymous, try it and see if it completes without error or blank page.
BTW, these guys are likely having issues and are trying solutions to solve them and causing side effects. Looks like they are trying to offer the kitchen sink. And the Apache Signature is giving away too much information (useful for us right now but not wise for them).
