A professor reported some problems with PDF files. I’ll need to actually see the problem myself to check out what the problem is. Here are some links to people posting about similar issues:

• Using Moodle: PDF issues – cannot open PDF: error “file is damaged”
• Someone in the above postings indicated that gzip compression being on could cause the problem. He suggested looking at the apache site: http://httpd.apache.org/docs/2.0/mod/mod_deflate.html
• Using Moodle: PDFs not loading with 1.9
