I dont know what happened but its not possible to change my events or add a new event anymore. Could it be possible that it is because i changed to a new provider? What do I have to check then?
Guys, you must have missed the announcements category posts about updates over the last couple of weeks. Update to the current DT Register and you'll find we loaded a new tabs script to fix this issue. Wasn't a DT Register bug... but any extension that used the Joomla tabs script in combo with the text editor will have this problem. So we loaded a different tabs script to use instead of the core Joomla script. This problem used to be rare but has become more common with recent browser updates.
Enabling that Mootools update plugin does help also. So you can do that, but we've made changes to get around the problem also.
