We are running the latest of version of Moodle 2.2 (updates from 2 wks ago). The environment is: WIndows server 2008 R2, SQL 2008 R2, PHP 5.3.8. We have been encounters two issues:
1. Some courses cannot be backup. We get an "Errror 500: internal server error". It doesn't matter if we use scheduled backup or manual.
2. whenever tinymce invoked, it will flash the html codes in the editing area for a sec or two, and then the tool bar will return.
Any suggestions? The site has been running Moodle 2.x since last year. We have verified that the server performance is not an issue.
