Caching & Minify Plugins (W3 Total Cache, Autoptimize, WP Super Cache, Comet Cache, Better WordPress Minify, etc)

Page Builder Sandwich works with all caching plugins. However, you might encounter some problems if you turn on their minify or caching functionality.

Autoptimize

Make sure that you exclude these Javascript files from being optimized by the plugin:

• page_builder_sandwich/js/min
• wp-includes
• wp-admin

You should end up with this:

W3 Total Cache

Make sure that Don't cache pages for logged in users is checked under Performance > Page Cache

If you're using minify, make sure that  Disable minify for logged in users is checked under Performance > Minify

Other Caching and Optimization Plugins

Just make sure that minify is disabled for logged in users, and it should work fine.
