I'm on a Mac and use firefox.
When you click on a photo within a post, it opens in a new window and enlarges as it should. Also when you click on the photo it will flash to the next one with the post. I am not using any gallery plugin just what wp offers. Also I am adding photøs to the post individually and not in a wp gallery.
Problem: In the new window the file name of the photo is above the photo and the photo is no longer displayed on a dark background.
I have a test site with all of the same plugins, theme and is also on wp 3.6 and this does NOT happen on the test site - photos within post when clicked on opens on dark background with no title above it.
Tried deactivating all of the plugins on the main site and no change.
I am out of ideas to try.
Can anyone help me. Thanks!
