Ok folks,
This is the first time in 9 months that I have had a problem with a Moodle upgrade. I went from 1.3.1 to 1.4 dev and I lost the ability to create backups and view user images on one of my sites!!
If I FTP the files from Moodledata, they look fine, but if I access them within Moodle they are corrupt. I thought this might be a permissions problem, but everything seems to be fine. My host requires 755 on main directories (moodledata) and everything else inside it is 777). One interesting note though, I installed the exact same upgrade to a different server and it looks fine, hmmmmmm.
The "bad" site is http://webclassroom.gis4u.com
and the "good" site is http://classroom.socialstudies4u.com
Any ideas?
Marc
