When I go into a page to edit it, and then click on Upload/Insert link to add media (PDF, image, etc). The Add Media lightbox pops up with the black title bar and X to close it, and the white area for the content to be, but there's nothing in there so I can't even select what to upload, or select anything that's already been uplaoded. It will sit there for days & just hang there.
This is something that happens in Chrome, Firefox & IE. Although in FF & IE, there's just a progress bar that comes up. It is also happening on the 3 or 4 different computers I have, that are all on different networks & locations. The only thing I haven't tested was on a different OS (all my computers are Windows 7).
I have upgraded & reinstalled WordPress 3.3.2 just to be sure that's ok. I have also updated my flash & shockwave plugins too.
I'm not sure what else I can do to troubleshoot this. Any suggestions/recommendations would be GREATLY appreciated.
