Maybe my question is a stupid question, but I noticed that in Apparence > Customize there are two “Colors” item.
It seemed to me that it wasn’t like that a while ago…
Is it all correct?
You will need to disable and delete the current GP Premium plugin you have installed.
Then download the current version from Accounts > Downloads on this site and install that.
Then in Appearance > GeneratePress uncheck Receive Beta Updates option.
