If your site show warning "RVsitebuilder version x.xx require PHP version x.xx - x.xx only. Please check your PHP version" .

You can check your PHP version as follow.

For EasyApache can change the PHP version to support system requirements from the cPanel -> MultiPHP Manager. Select domain -> Choose PHP version to match the requirement -> Apply.

For CloudLinux can change PHP version to support system requirements in cPanel -> PHP Selector.

Select PHP version to match the requirement -> Set as current.

Go back to RVsitebuilder 7 to create site again. It will work properly now.
