This article was written for Page Builder Sandwich 5 or earlier. Page Builder Sandwich 6 is a new block builder, so some steps and screens here may differ. Getting started with version 6
PHP 7
We have tested Page Builder Sandwich with PHP 7 and everything should work fine without any problems.
Be careful when upgrading your site from a lower version to PHP 7, as there are a lot of incompatibilities with lower versions that should be addressed in all your themes and plugins.
