Hi,
On site is installed THEMIS template ver. 2.0.0 and Helix Ultimate with last update 2.0.12
Joomla 3.10.11 PHP 7.4.33.
When I add some images to Gallery Addon it does not work properly. Images are displayed, but I dont have arrows "back", "next" and on top "close".
After click I can see only one image, and must click back in chrome/firefox
I try to check on your template page how addon is displayed
https://demo.joomshaper.com/?template=themis >addons>gallery, but there is error:Page Not Found and You are not authorised to view this resource
Problem is here:https://pgwkancelaria.pl/pl/aktualnosci/konferencja-forumdlawsi-wyklad-mec-krzysztofa-piotrowskiego
There is 14 images in one gallery.
