I upgraded from 1.8.3c (was working fine) to 1.9.0a and everything works except for inserting an image using all 3 editors. When I want to insert an image the "loading" dialog never finishes and I am unable to insert an image. I have tried deleting my cache and using firefox as well as IE to see if it may have been browser specific. Unfortunatly, none of my attempts fixed it. Here is a screen shot:
I also noticed in the lower corner there was an error on the page, which revealed on line 279 of the image_dialog.php file had an error.
I'm not sure what I need to do to fix this and hopefully someone can help me out! I did see a different post similar to this regarding the @gui functionality, but I don't think this is the same issue. Any ideas?
