Hello,
I see you use the N8 for joomla ...
I'm trying to edit an article of joomla 1.5 with the Nokia N8, but when I write or modify the body of the article .. will not let me write anything, because I do not activate the keyboard ...
have proven to install the Mobile module joomla, but still I have not properly configured ... or I do the same ..
can you help me?
thanks
