Hi Gerben,
I’ve got a similar problem here. After I installed your “plugin Magic Gallery”, I was not able anymore to add links via the RTE.
When I select text and hit the “Link”-Button, the normal window pops up,but the Button “Link hinzufügen” (Add Link) is replaced by “Aktualisieren” (Update/Refresh). When clicking on this button, the current site gets updated, but theres no link.
When I disable the plugin it’s all normal again and working fine.
Do you have an idea to solve this?
