Missing Theme Options / Customizer or UX Builder

If you get a blank Theme Options screen or have problems opening UX Builder try these steps:

1) Increase memory limit:  Increasing the WordPress Memory Limit. It's recommended to have at least 128mb.

2) Make sure you have at least PHP 5.6 installed. You can check that in WooCommerce > System status.

3) Make sure you have at least WordPress 4.5 installed.

If that does not work there is probably a plugin conflict. Try this:

1) Disable all plugin.

2) Check if you still can't open the Customizer or UX Builder.

3) If it works try add activate the plugins again one by one and test.
