I'll explain what my problem is. I have been running a Moodle (2.9) site for 6 months now without any problem. Everything ran smoothly until one day I noticed that I had problems to delete students from the site. I clicked on delete student from site and, even though the student was deleted, the Moodle Site crashed.
The problem I have now is that I am not allowed to run any tool in the Administration Section, for example add or delete courses. The site crashes and I get the error in the attached file in this forum. Does anyone know what may be wrong or how I can work this out?
There are not many students (90) and the host service has just been updated to a faster service to see if that was the problem, but nothing happened.
Thanks to you all in advance.
