[lug] php hosed!?

[Deva Samartha]

I tried installing imp with horde and now php does not work anymore - the 
php code is displayed in the browser window instead of the generated page.

I installed a phplib and that may causing it since I changed the altered 
config files back.

Are there any php error output logged in a file?  The apache configuration 
has not changed and it was working before....

Anyone any ideas??

Thanks,
