I received this error when I try to access the component in admin.
Fatal error: Cannot make static method JToolBarHelper::addNew() non static in class mosMenuBar in /var/www/training/administrator/components/com_uddeim/admin.uddeimlib15.php on line 27
I get this error in frontend:
Fatal error: Call to undefined method JLanguage::getBackwardLang() in /var/www/training/components/com_uddeim/uddeimlib15.php on line 174
Are you sure that you have 2.5b installed? It seems that in "toolbar.uddeim.php" the wrong library is loaded. This is a first time report so I think it is something with your installation.
Please try to redownload the uddeIM package from my dev site and do a clean install. You should also try to install it on a fresh Joomla setup.
