I have a problem adding a picture to a post after updating to WP 3.6 (problem appeared after maybe 2 days after update).
I can upload an image without a problem, I can see it in media library, but when I edit a post and press Insert image button, window opens but is blank - there are no images at all so I can't add any :-(
I tried a lots of things - tried to disable all plugins (didn't help), tried DEBUG mode and cleared all problems (didn't help), but then I tried to switch to different theme and voila, I can insert image to post normally.
Does anybody know, where in theme files can be the problem? I really don't know where to look :-(
Thank you in advance!
