I just upgraded media from unstable 6 to unstable 7. Now, when I go to insert an image, if I click on 'Library', I get a dialog box with the error 'Error getting media'. If I try to upload a new image, as soon as I click on submit after choosing the image, the dialog box goes away, but there's still the opaque overlay on the edit page.
I've tried uninstalling the module and re-installing it, but that didn't help at all.
Any ideas what I may have done wrong?
