Hi I have the following setup:

- Ubuntu 10.04 LTS
- Apache/2.2.14 (Ubuntu)
- PHP Version 5.3.2-1ubuntu4.5 with eAccelerator v0.9.6.1 and Zend

On the server I am running a WordPress MU instance with no problems that I can tell and am trying to setup OpenX.

OpenX appears to have installed correctly (I can login etc.) however when I view certain pages like the statistics page (stats.php) it directs the user to download the .php file in Firefox (unless I am logged in as an Administrator) instead of executing it.

Safari does something slightly different and returns:
"Safari can’t open the page “XXX” because the server unexpectedly dropped the connection. This sometimes occurs when the server is busy. Wait for a few minutes, and then try again"

PHP on all accounts appears to running fine (no errors) and apache is just logging a 200 (ok) request.

Any help would be greatly appreciated.

UPDATE - Appears to be an eAccelerator Issue
