You might have upgraded recently but for some reason the plugin is still asking you to upgrade or some columns and features are locked. Do not worry, there are two reasons why this may be happening:
You have the free version still installed
To uninstall the free version, go to your WP Dashboard > Plugins > All Plugins > Look for our plugin > If the plugin doesn’t have the word “PRO” or “PREMIUM” in it’s name, it means that is the free version and you need to uninstall it. If you haven’t installed the PRO version, you received the download link via email after the purchase and you must install it.
The license is not active
Go to your WP Dashboard > Plugins > All Plugins > Look for our premium plugin > it should show an “activate license” button, you need to enter the license you received via email.
