I activated the uni-signing plugin. Add the facebook app ID/Secret in the /sys/Ext/hybridauth/config.php

then I have a error 500. I get this in the logs:

httpd: PHP Fatal error: Class 'Hybrid_Exception' not found in /home/httpd/vhosts/xxxx.com/httpdocs/codoforum/sys/Ext/hybridauth/Hybrid/Endpoint.php on line 213

hybridauth forum indicates:

It seems that your autoloader not working properly or you don't have one at all.
And if anything not expected happens, you can't handle that because exception class not found.
Just fix your autoloader.

is there a bug on unisign tools?

thanks

Are all other pages in the forum working ?

Can you try with a fresh install of codoforum ?

Hi,

Yes, all pages are working. And the facebook login worked on the Vanilla Forum I also installed on the same server.

check:

thanks

This error means there is a problem on the server side. A server error can be caused by any number of things from uploading the incorrect file to as bug in a piece of code. This error response is a generic "catch-all" response. The web server is telling you that something went wrong, but it's not sure exactly what that is.
