I'm using Moodle 2.4.5 and I'm having a problem with IE (8 or 9 didn´t try with 10). When I try to edit a course, insert a file or other activity or resource, when I click in save and return to course the block of the left side disappear and a white space is in the right side of the screen. As the picture shows:
I have to turn editing on or refresh the page so that the left blocks appear again:
The theme selected and modified is Zebra theme but if I change to formal white with no changes the problem is the same. I have no problems with other browsers.
We are upgrading Moodle to 2.5.3, in a test server and the problem still remains, can anyone help me?
