@phit I'll give that a go, thanks!
Edit: solved my issue, thanks! However I'm still curious as to what caused the issue in the first place...
How to add the Solved/Unsolved badge to NodeBB topics?
Hello @H7 -- you'll want to use the Q&A plugin: https://github.com/NodeBB/nodebb-plugin-question-and-answer
You can find it in the Plugins menu, or if not, then you can likely install it via npm.
@julian Thank you!
