Then try to manually remove following files from administrator/components/com_mobilejoomla/markup directory:
chtml.php
iphone.php
wml.php
xhtml.php

The only 2 Files i have and had in this dictionary are:

mobile.php

tablet.php

 So the problem has to be somewhere else.

Thanks for a fast fix of my problem...



Mobile Joomla was working fine before 2.x on my site and since the update to 2.x about 3 days ago is it not working anymore...

need this website running mobile again as fast as possible
 (it's a business Page)

Hmm, that is quit stangely because of MJ 2.0.12 checks that class MjMarkupGenerator_... is declared before instantiate corresponding object, so that in the case of incorrect markup value it fallbacks to desktop version.

Could you list all plugins of "mobile" type enabled on your website?

Sent you a private message, since i'm currently busy with clients can i not check it right no my self...
see PM 

Problem is now halfway fixed...
can see the entry Page, but when i go to any menu (to see a submenu or a content) os the page just blank and i don't see any content or menu...

any help?
