Hello,
I am Vladimir from Smartsupp. Happy to hear you have resolved the issue.
Just a note, if you have WordPress version our plugin doesn’t support, you can always insert the code manually. Simply copy-paste it before the closing </head> tag in header.php in WordPress editor. Inserting the code manually works on all WordPress versions.
In case of any questions or issues with our plugin you can contact us on chat on https://www.smartsupp.com.
