Many users contacted us with regards to an error while using Convert Plus and WPRocket on the same website.
While we are working on finding out a permanent solution for this, the team at WPRocket has announced a workaround that will allow you to use both the plugins together on the same website.
You simply need to disable one option in your WPRocket settings.
Go to File op0timization -> Basic Settings -> Combine Google Font Files
Disable this option.
