Error : add email and license key when add section in page

HI

​First you have to download SP Page Builder Pro from here
https://www.joomshaper.com/downloads/extension

​Then you have to install it. Go to administrator-->extension-->install

​After that you have to active it.Input your email and license key to SP Page Builder -> Pages -> Option (on the right) -> License & Update (input your email and license key) -> Save and Close.

Your License Key is located in your Dashboard.

​Then Clear Joomla and Browser cache.
