Apache php problems after updating

For some reason I cannot access my webpage in the regular way. When I go to http://wieisalbert.nu it shows me the plain text of the php-file. This happened after i recently installed a whole bunch of updates.

I did:

• Virtualmin > System Settings > Re-Check Configuration
• Virtualmin > Limits and Validation > Validate Virtual Servers > Fix Permissions

Both are correct now, but still it shows just php.

However, if i do change the apache configs for the virtual servers manually (ie removing the 'removehandler' parts) it does work. But how can it be that it doesn't work in the regular way? I also tried to make a new virtual server, but on that one it doesnt work aswell.

Thanks in advance
