I imported several Content Templater items from one site to another one of mine.
Alright.
But now I can't insert ANY item in a custom module: the insertion hangs until I press a key. But no content inserted.

Fascinating!
Most of the buttons no longer work.
The Regular Labs ones, the Joomla core ones like Article or Contact and so on. Image Effect CK works just for the first time, then no longer...
If I cut and paste the HTML code, Content Templater works.
I can't figure out the reason...

Thank you so much, Peter
