problem with media manager

Hi,

first, thanks for this awesome plugin, it helps me to do what i need and what i was searching for a long time.
But, i have a problem with the media manager. When the plug in is active, i am not able to add an image in a post for exemple. I can upload the image but when i click on “insert the image in the post”, nothing happen.
I am sure the problem is only reproduce with the plugin.

Thanks for your help,

best regards

Cédric
