Hi Tim,
Thanks for reaching out with your BoldGrid Post and Page Builder questions! Since you’ve already identified a clash in functionality between PPB certain third party plugins you should now enable WordPress debugging to check for specific error messages. Add the following to your wp-config.php file:
define( 'WP_DEBUG', true );
define( 'WP_DEBUG_LOG', true );
Reproduce the error, then check the wp-content/debug.log file for details. If you can copy/paste that error log into the thread here we can inspect it to help you determine exactly what’s happening.
Thanks Tim, hope to hear from you soon!
