Cannot upload anything - buttons not working

Hi.

On our site, we are not able to upload anything. Mainly because no buttons are working. We can create albums, but not upload - the button ‘select images’ does not work at all, nor does the drag-and-drop function. In BuddyPress we cannot upload images to the activity stream neither. On som computers, there seems to be an indicator stuck at 100%, showing some blue circles going round.

Hi kenneth,

Which version of Internet Explorer are you using? and have checked if its working on any other browsers or its just Internet Explorer?

It seems to be a problem in ie9 and probably also ie10, because it works fine in safari and firefox on mac.
I have also tried ie11, and it worked flawlessly. As for now, i will tell our users to upgrade ie or use another browser.
