Hi,
Just upgraded to JFBC 6.0.4. I use it with EasySocial 1.2.7 and now when I log in with the ES button integration or with a JFBCLogin tag i get the Joomla error message "Warning: Copy Failed". See attached screenshot.
I saw an old post where this was caused by a Kunena plugin and was later fixed. Wonder if JFBC 6.0.4 is trying to pull something in from EasySocial 1.2.7 and can't?
Note that this happens for both FB and G+ logins. Haven't tested with Twitter.
