Thank you all for your earlier replies. I am running PHPNuke 6.5 and Coppermine, but don't seem to be able to get them to intergrate. Admittedly I have got effectively no knowledge of PHP and am learning on the fly, but I am not sure what I'm doing wrong...
Has anyone else used this combination on Dreamhost? And if so, what did you have to do to make it all work correctly please?
Thanks again, Bill
