Open Source Document Management System | OpenKM

Hi. I have a huge problem with my OpenKM
In friday I cant upload document (in Internet Explorel only). OpenKM shows my error like in attachment (image001).
Today, I cannot log in to OpenKM (Internet Explorel only). I have an error like in image002.
Can anyone help me?

Try to clean the browser cache and test your network connections.

Still I can`t log from Internet Explorel.
InvalidCharacterError
code 5
Have any idea?

Do you got some ad killer, antivirus or similar. Try to disable any software which can kill ajax networking calls.

If it's possible, I suggest try with a clean computer client without anything installation.

Ok, i switch web browser to IE9 and itd works. Thanks for help

Edit: In compatibility view works too
