Thanks for your response!
So I would start writing the stuff... but I'm afraid it would be then limited to the functions that I'm using for my site, and of course some explanations depend on the theme that I'm using 😄
Bloody hell! I took out the recent replies option on the category causing trouble. I changed it from 2 to 0 and that solved the issue. I was able to activate the category again and everything is back to normal.
I'm guessing the poll was bothering the preview on the homepage.
NodeBB plans range from $35 to $100, depending on the feature set.
$75 and up plans give you advantages like custom DNS forwarding (so you can use something like mypersonaldomain.com instead of myapp.nodebb.com) and daily backups. All plans come with use of the support ticket system, so you can reach us for support for individual instances.
