Hi rare ,
Thanks for the link!
It does not seem like the Buttonizer code is on the site right now.
You mentioned that you installed the new version, is this version perhaps version 3? If so, were you able to connect your Buttonizer account? If you are connected to a Buttonizer account, the Buttonizer plugin's dashboard should look something like this;
If you are already connected your Buttonizer account, could you perhaps clear the cache on WP-Rocket?
It may be cached and that's why the Buttonizer code is not on the site right now. 🤔
Let me know how it goes! 😄
