Hello.
Our plugin does not have a separate premium version. You bought the plugin from another developer, but the plugin's slug matched ours.
You can try our plugin.
Most likely, for requests from third-party services, the server asks you to enter a captcha. Perhaps this is DDoS protection
In any case, you can disable the plugin and check if it solved the problem.
Hello.
At the top of the optimization page, select the premium server.
After that, restore the backup in the plugin settings and run the optimization again
Hello.
The Premium plugin is not a separate plugin. This is an addon to a free plugin, so the free plugin must also be activated.
Deleting snippets when deleting a plugin is configured in the plugin settings.
