I am using JFBC, and SC Login and Quicklogout plugins. I recently changed my primary domain and SSL from olddomain.uk to newdomain.com. My problem is - the Facebook login via JFBC is redirecting to
www.olddomain.uk. Also, after logging out of Joomla, user is redirected to
www.olddomain.uk. I have checked everything in Joomla3.x to be in order, changed everything right from .htaccess, logs and tmp folders, replaced all instances of olddomain.uk in all Joomla files and the database. I have changed all JFBC settings, which does not show any errors. .htaccess is empty. I contacted host support, they said its not a server issue. Please try to solve it as soon as possible.
