I am having a strange issue, that just started a day ago. We are running Moodle 2.7 with over 1400 courses. Everything has been running great all year, until yesterday. There are two courses that when you try to access gives you a Page Not Available or Connection Reset error (depending on browser). The Strange part is if I navigate to the settings page, assignments page, or even a module inside these courses I can get access, but I can't get to the main course page. I have made a backup and restore it to a different server and still get the same issue. Has anyone had this happen to them?
Thanks for all and any help!!
