I tried disabling all other plugins and it made no difference. Is there maybe a logfile to check to see if anything is wrong? I keep getting “No access token receieved!”
I tried inserting the company on another website and that worked, the only difference I see is the WordPress version.
Wordpress Version of the site that is working: 4.5.4
Wordpress version of the site not working: 4.6.1
Does this plugin need an update perhaps?
