mod_suphp kills your website on Plesk 9
This doesn't only happen in Plesk apparently as I have seen it reported with cPanel.
Essentially, after installing mod_suphp, if your website starts throwing error 404s when calling a file and shows the Plesk default page when visiting the site root, it's probably because the www prefix wasn't properly configured during domain setup. Essentially this is the same problem and solution as my last post, which was handy, cos I already had the solution once I worked out what the hell was going on, so see that post for the answer:
