Session id errors when using with Ultimate member plugin

Hello,

I’m trying to use your plugin with Ultimate Member and after i activated plugin and entering Facebook,google details, When i go to login screen, I get this error:

Warning: session_start(): The session id is too long or contains illegal characters, valid characters are a-z, A-Z, 0-9 and ‘-,’ in /home/premiumindia/public_html/wp-content/plugins/wordpress-social-login/wp-social-login.php on line 64

The error still shows after i deactivated Ultimate member plugin.

Please provide some solution, I would really appreciate it.
