Same issue that seems to be related to Bootstrap Styles ^1.1 → ;
this patch can help!

Confirming this patch worked for me, very helpful thanks! Not sure if it's related, but in order to edit the section afterward I also needed to apply this patch for media_library_form_element 🐛 Deprecated function: explode(): Passing null to parameter #2 ($string) of type string is deprecated Fixed . Otherwise clicking "Configure" did not bring up the dialog overlay.

Yes, I confirm that what @yospyn said is correct. I personally applied the patch reported in the #4 🐛 Live Preview has issues with Media Background Fixed comment.

✅ Released bootstrap_styles 1.1.5 →

Automatically closed - issue fixed for 2 weeks with no activity.
