I'm having a problem with my installation of Moodle 1.7.1+ on my hosted Linux server. I've just upgraded my 1.5.4 installation and everything seems to be working perfectly, except when I edit a course.
When I turn editing on within any course, all the topics within the course dissapear and the only thing I'm left with is the two forums within the first block, the rest is blank apart from the left hand blocks. All the right hand side bars also disappear. Everything returns when I turn editing off.
This is common across all courses and also when I add a topic section to the front page. I'm using a hosted Linux server using PHP version 4.3.9
Thanks in advance for the help
