Hi Ronny,
Yes, Showtime Image Gallery is Joomla 4 ready since day 1 of Joomla 4 release. This issue was introduced 3 days ago, when Joomla 4.3 was released. Showtime Image Gallery is working perfectly with all 4.x versions prior to 4.3.
In any case, I have applied a fix for the next update which will come out very soon. If you cannot wait until then here is what you need to do:
Edit file administrator/components/com_showtime/js/showtime.js
1. Replace line 15 contents with the following code:
this.$editModal.appendTo('form[name="adminForm"]');
2. Replace line 17 contents with the following code:
this.$progressModal.appendTo('form[name="adminForm"]');
After you apply the changes you may need to clear your browser cache.
If all that sounds too complicated, please create a
private ticket and provide FTP access to your server so I can do it for you.
Note that this will fix the issue preventing you to edit the gallery. The custom field connection issue is something different and probably has to do with the update. Are other custom fields working? If other custom fields are working after the update then Showtime Image Gallery custom fields will work too.
Regards
