Forum 4.0.0 to 4.0.3 PL4 update. Site dead
 

Hi,

After upgrading the site from 4.0.0 to 4.0.3 PL4, the site is now "gone".

I can reach the adminCP login, but after logging on I get a blank page. Same with the forum and CMS pages; blank pages, no message. The web server returns the HTHM head an body tags but nothing else.

Please help! Where do I start?
