We transferred hosting of our site from one GoDaddy account to another. They transferred the Moodle site as well. They helped me go into the config.php file and make a few changes there. We could access and use the Moodle site BUT... ever since then many of the images (like photos for each user profile) would not show. Instead only the text (like "Photo of John") shows instead. We had put up with this up until now but then today tried to do a backup of the course. When I clicked the final Continue it stopped and received the following error message: Can not read file, either file does not exist or there are permission problems.
My guess is something isn't pointing to where those images are kept?? I am not a php person but could get by at editing if given where to look .
