Hi Seolife ,
Thanks for reaching back out to us!
Did you perhaps see this error message in the Developer tools -> Network of your browser?
I believe that that error message happens when an integration code is used that does not exists.
Could you try to copy and paste integration code of your site again into the header or footer of the site?
Or if you are using the Buttonizer WordPress plugin, reconnect by going to the Plugin settings -> Disconnect then reconnect again.
Let me know if this helped! 🙂
