Ajax infinity error "Failed to load ressource"

Hello

i just installed Ajax infinity on my page. but it shows an error i tried to look in the console in safari it says this:

Failed to load resource: the server responded with a status of 500 (Internal Server Error)  site.dk/index.php/2?start=10&ajax=1&_=1457558735804

you can find the plugin installed on this page:
goo.gl/3B2ONT

i tried to disable the plugin, and there are no errors after i disable it. so the only js error is because of the plugin. im running joomla 3.4.8

Can you please send an email with Joomla admin credentials? I will have to take a look on the settings.

hello. i sent you a PM with the password and username.
