I'm running Moodle 2.5+ (not the latest version that just dropped). I installed the FN -Tabs Course Format using the update module that is in administrative settings. I uploaded it from the Zip file. It appeared as an option, but when I go to edit the actual tabs, by using the little editing wheel to the side, I am directed to this site: http://mydomain/moodle/course/format/fntabs/tabsettings.php?id=3
and get this message: 500-INTERNAL SERVER ERROR.
I don't know code but if someone can help me I'd appreciate it. Could it be that the plugin only works with the newest moodle version? If so, how do I uninstall this plugin?
