Help!  I was just cruising along today adding content to a new site and the Telerik Image Manager suddenly stopped working the next time I tried to use it.

Thinking something got clobbered on the site, I tried the same on my localhost installation - same problem!!  Tried it here on this forum - same symptom!

Here's what I've tried so far:

Browsers:  Firefox 3.6.12, IE8
Rebooting local computer
Restarting DNN on remote computer

Anybody have any ideas??

Thanks, Marty

Ok, here's a little more info - there's an error in the event log

Can someone point me in the right direction here?

Hi Sebastian,

Thanks for confirming where I was headed already - unfortunately the improved editor showed the same symptoms. I'm guessing this isolates the problem to the underlying RadEditor and not the provider, correct?

Anyway, the Config module provided with the improved editor did make it easier to switch back to the old faithful FCKeditor - that's my workaround for now until I can get this issue untangled.

Cheers from Colorado,
Marty
