From the visual editor, when I click on an image I get the icons to edit or delete. Delete works. If I click "Edit Image" I get the Lightbox popup, a slight delay, then a "Not Found" page.
I've compared the iframe to one on another blog that works. The broken one has this for the iframe address:
The working blog has this for the iframe address:
The only reference to 'editimage.html' appears in
In both of those the link shows up as 'editimage.html?ver=321&TB_iframe=true'
You'll see that the parameter 'TB_iframe=true' is missing from both the address of the iframe on both the working and the broken versions.
I've tried modifying both of those files to see if I could change anything, and the address kept coming up the same. The files seem to be caching somewhere but I can't find it. I've tried enabling, disabling and clearing SuperCache, and cleared browser cache.
I've tried disabling all plugins. I've tried with multiple themes, including the one that works on another blog.
I'm out of ideas. Anyone know where I should be looking?
