"Incorrect usage of Mobile Joomla." without using mj!

Hi,

here's my example link:
privat-kliniken.net/index.php?option=com_content&view=category&layout=blog&id=23&Itemid=25
If u click on any "Weiterlesen: ..." link, u get an error:
"Incorrect usage of Mobile Joomla."

But tthis part of joomla is only for normal browsers, I'm using extra menus for mobile joomla.
So there is no mobileJoomla, but I'M always getting this error. Why?

This error still appears if i deactivate all mbole joomla plugins!

Maybe you assign one of MobileJoomla templates to that menu item...

I think I have managed to reproduce this.
It may be because one of the 4 mobile templates has
menu assignment (select from list)

Could you set them all to
menu assignment (none)
save
and then
menu assignment (select from list)
but do not select any menus
save
and see if the problem goes away?

The assigned tick goes away on the template page but I don't think that matters.

great minds think alike
