After updating to the latest JCE editor version Pro 2.9.92 we get an error on all our sites when trying to open the file manager / browser:

Error: Attention -> error

URL: administrator/index.php?option=com_jce&view=browser

In the console:

I have the same problem. JCE 2.9.92

I checked, the last working version is pkg_jce_pro_2989.

Uninstalling and reinstalling did not work for me. Ik have just send you login details for our demo site.

The JCE Pro 2.9.93 Beta 1 indedd fixed the issue. Thanks Ryan!

Hi,
I installed the 2.9.93 Beta 1.. but still my folders are gone in the file manager...

edit: its the one under "image and links" 

there is only the "startseite"  and "= Folders" (see image 1).
I cant choose another folder.

yesterday (before the update) there were all the folders (like in image 2, image manager)

well, for choose image in editor, but not for the article image (intro image etc.) there are no more folders...

cleared Browsercache.. still no folders.

I cleared the path to the intro image, saved the article and then click to choose a new one and the folders are back again... no clue what kind of behavior this is...
