Just upgraded to 3.6 and when i try to edit a gallery on a page, there is no way to edit the gallery. In the VISUAL view, where there should be a box that holds the gallery, there is nothing... in the TEXT view, i can see the gallery code.
I am not using any plugins other than:
Jetpack by WordPress.com Version 2.3.3
Velvet Blues Update URLs Version 3.1
WordPress Importer Version 0.6.1
WP Lightbox 2 Version 2.28.3
Turning them off does NOT fix this issue. Deleting them does NOT fix this issue. Reinstalling wordpress 3.6 does NOT fix this issue. Reinstalling the plugins does NOT solve this issue. Clearing browser cache does NOT solve this issue.
