I have a problem on this plugin.
I have 2 wordpress site which is ‘www.she.com’ and ‘usersync.she.com’ (cannot reach because I changed local host table), ‘www.she.com’ as master.
I am following the documentation guide pass Master site url and key to sub-site, unfortunately I got a message “There was a connection problem. Please check the URL and Key of the Master site” after synchronization.
I already enable “Debug mode” but still cannot see any log from plugin file.
