Blank frontend and backend if mods are activated

[rotor]

Hi,

All of a sudden without making any changes to my site, my site went completely blank - no front end or back end. After advice I disabled mods in my config.php file.

I have vbAdvanced CMPS on the front of my site so after disabling mods I changed the VB index file back to index.php and renamed my CMPS index file to get it out of the way while I looked at things.

Ok, after that I can access my backend and the forum. I have disabled all of the mods in the vb backend but when I enable mods in the config file I get the blank front and backend again ...

I'm at a loss to know what is causing this .....

Any advise would be appreciated
