[Resolved] Fatal error: Call to a member function get() on a non-object in .... /plugins/mobile/always.php

I have install mobile joomla in my joomla 1.5.24 website (www.quilles.net). On my phone I have this error : Fatal error: Call to a member function get() on a non-object in /homez.18/quilles/www/plugins/mobile/always.php on line 24

Thank you for your help.

This is know issue and it will be fixed in MJ 1.0RC5.
Current solution is to open Mobile-Always plugin settings and click 'Save'.

It's ok now, thanks
