Hello,
by chance do you know why all the contents (categories, articles, items ...) have disappeared from the two lists of contents to be selected for viewing in the Zentools2 module? I updated Zentools2 from version 2.4.3 to version 2.4.4, and then I updated Joomla from version 3.8.12 to 3.8.13, and nothig is changed. The template is "Wedding". There are no warnings and database is ok. PHP is 7.2.10. As you can see in attached screenshot the 2 list of Zentools2 contents are empty.
Thanks!
