Fix'd, was something with the plugin, Not sure exactly.
I've uninstalled and install the composer. But not sure why but once I rebooted Unbuntu itself it seemed to kick something free.
Sorry, but I can not figure out where to enable recent topics like on the screenshot:
@henrywright Thank you.
Do you know where or how to translate "Recent topics"? I need this string in some other language.
psychobunny/nodebb-plugin-recent-cards#6 when merged will allow you to internationalise the plugin.
