My hoster Siteground this week started promoting the ability to move sites to PHP 7. (https://www.siteground.com/blog/wordpress-on-php7-now/). They released a plugin that will validate whether your site is ready for PHP 7 or not. Sadly it found issues with Workality and Visual Composer.

The plugin is: https://wordpress.org/plugins/sg-cachepress/ but it only works on sites hosted on SG. I've posted the issues below.

Are these known issues? Can I ignore them and move to PHP 7 anyway?

Thanks,
Ben
