Hi, there seem to be occuring something similar to [[ https://phabricator.wikimedia.org/T43937 | this previous problem]]
On cswiki with IE9 I have problems starting yesterday with loading edit panel. To be more precise, the panel does not load at all. When using F12 I can see following error **SEC7115** I am no expert on programming and I am pretty disturbed by not being able to edit wikipedia properly. Feels like it is 1985 and not 2015.
