The Facebook extension is www.oneall.com/

K2 is K2 v2.6.8

With the firewall disabled I still have the same issue. It says for a second you are logged in with Facebook then goes to the error page. I t does register you on the back end though.

It sounds like an issue with the extension. It probably does not support K2.

You can try disabling the Enable K2 User Profile setting in K2's advanced settings.

I am using hot destinations 25 on Joomla! 2.5.28 with K2_v2.6.8.

Hi everybody,
i'm trying to migrate a website on a dedicated server. The website perfectly works on the old server. In the new i only can see that line:
Fatal error: Class 'K2Model' not found in /var/*****/****/*****/httpdocs/plugins/system/k2/k2.php on line 430

And the same is for admin panel. I checked the php version and it's the 5.6.27 one. I cannot access to anything. Is there some parameter i have to check in the plesk panel?

Thank you an regards,

Marietto

Which K2 version were you using in the old site?
