I have no idea why this is happening. I've read A LOT about it and there don't seem to be any solutions. I once read that it was expected behaviour because of some plug-ins and that the Hotfix plugin would fix it but that wasn't the case.
However, if I go to the actual media gallery through the sidebar, I can see all my images. I've tried searching and filtering the page in the image but still no images show.
Any one familiar with this problem and know of a fix?
