After downgrade from Evoq Content to DNN CE 7.4.2 the html editor doesn't save any changes: the modal window remains opened after press SAVE button. This happen using both CKEditor than RadEditor. I tried to reinstall module after delete HTML folder in DesktopModules but the error is still present!

I'm sure the downgrade is ok, there are no professional references in installation.

Please help me.

Thanks
