Thread:Project:Support desk/Compatability issue with PHP53 and mediawik 1.19.2 on SLES 11 SP2

I have been working on upgrading from Mediawiki 1.15.2 to 1.19.2 on SLES 11. My server is running Apache2 with PHP 5.2.14 with Suhosin-Patch 0.9.7 (cli). I have successfully upgraded to mediawiki 1.19.2, but when I upgrade to PHP 5.3.8 I have issues. After the upgrade, any time I attempt to load a .php page I get a popup window asking me what I want to do with the file. I have done all of the upgrades with yast. Any help would be appreciated.
