This is a strange one. My colleague is unable to add an image to a post but I can, even with his login! It's possible it might be related to our institution's network logins but I can't think in what way...
He is able to upload an image the problem occurs when he clicks on "Insert into Post". instead of adding the image to the post, the insert window remains visible but goes completely blank and nothing happens. If anyone has experienced anything similar or have any thoughts we'd much appreciate it.
Cheers
Matt
