Hello,
my page is running SP Page Builder 3.8.9. the AddOn Modal Popup is working fine if my page is running Joomla 3.10.11.
After update to Joomla 4.2.6 the AddOn is not working any longer. After klick on the button no window ist opening. Between both versions there was only the update to Joomla 4 no change of modules of SP Page Builder.
Best regards
