Hi,
In that post moderator named “günter” says:

If you do not want to wait for the next update you can replace the complete content of file enfold\config-templatebuilder\avia-shortcodes\gallery_horizontal.php

with the content of “RAW Paste Data” in

https://pastebin.com/gpamiBuJ

Make a copy of the original file to have a fallback in case something goes wrong. The link is valid for 1 week.

Check the input fields in the element.

Let us know, if it solves your problem.

That pastebin link code is not avalaible now. Thats what I lookin for.

Thanks.
