I would like to use the Module JoomlArt Advanced Custom Module with Type Gallery and Style-1. But every time when I try to save an error appears. Unfortunately it's only written Error nothing else. The other Types like Slideshow work fine. I have Joomla Installation local 3.9.4 there it works fine but on the Server with newest version 3.9.5 it doesn't. Any succestions how to fix it?
