@azeus looks like this plugin without localization,
You need change this file:
Recent Cards Plugin: 2.0.10
Theme: Slick Theme
I'm having the very same issue as @Per0x here:
When clicking on next/prev button of the slider, the page will reload (indicated by the progress bar at the top) and you end up at the initial slide.
Anyone has an idea how to fix that?
You need to upgrade to latest nodebb for the latest recent cards plugin. If you want to stay on 1.14.3 downgrade recent cards to 1.0.13
