Elegant Themes Extra Wordpress Theme 4.25

- Fixed "Call to undefined function et_fb_enabled()" error that occurred when using some third party plugins that modify the WordPress loading flow.
- Fixed a bug that made it impossible to disable the Divi Builder if the original version of the page being restored contained no data.
- Fixed compatibility issue with BackupGuard and other plugins that caused the Divi Builder to fail when attempting to edit modules due to the de-registering of the WordPress heartbeat.
