I think I need to tweak something, either on the server or in Moodle, but I'm not sure where to start.
I have two servers, both Linux/Apache. On server A, Moodle works like a charm. On server B, it installs and appears to work, but virtually all non-html resourses display as text. For example, a PDF doesn't invoke Acrobat. It brings up an ASCII display of the Postscript code. The server itself is fine with PDFs, because I use them elsewhere on the site with no problem.
The two Moodles are absolutely identical (v1.2). I copied exactly the same files to both servers.
Any ideas? (Both are shared servers, so I have minimal control over Apache settings.)
