Hi,

I just first time installed K2 on my Joomla 2.5.8 and now I tried to add new category ! When I press "Save" I'm redirected to www.xxx.lv/joomla/administrator/index.php blank pake. When I go "back" in my browser, I land again in Category view and basically it's not saved.

What can cause such behavior? Need I somehow configure K2 installation, enable some plugins or what..?

I'm getting:
Fatal error: Class 'JdFinderIndexerAdapter' not found in /var/www/vhosts/edgetech.lv/httpdocs/joomla1/plugins/finder/jdcontent/jdcontent.php on line 37

Try to disable the plugin jdcontent
