    @cagatay The most reliable way to upgrade Node.js on Ubuntu depends on how you originally installed it. Method 1: Using NVM (Recommended) If you already use Node Version Manager (NVM), upgrading is simple. NVM allows you to keep both versions and switch between them if needed. Install Node 22: nvm install 22 Switch to Node 22: nvm use 22 Set it as your default: nvm alias default 22 Verify the change: node -v Method 2: Using NodeSource (PPA) If you installed Node.js via apt using the NodeSource repository, you need to update the repository script to point to the new version. Remove the old NodeSource list (optional but cleaner): sudo rm /etc/apt/sources.list.d/nodesource.list Download and run the NodeSource setup script for Node 22: curl -fsSL [https://deb.nodesource.com/setup_22.x](https://deb.nodesource.com/setup_22.x) | sudo -E bash - Install/Upgrade Node.js: sudo apt-get install -y nodejs Verify the installation: node -v Method 3: Using the ‘n’ Package If you have npm installed, you can use the n interactive manager. Clear the npm cache: sudo npm cache clean -f Install the ‘n’ helper: sudo npm install -g n Install Node 22: sudo n 22 Update your shell: hash -r Troubleshooting Permission Denied: If you see permission errors using Method 2 or 3, ensure you are using sudo. Path Issues: If node -v still shows version 20 after upgrading via NVM, restart your terminal or run source ~/.bashrc. Conflicts: Avoid mixing these methods. If you switch from apt to nvm, it is best to sudo apt remove nodejs first to avoid path conflicts.

    @Panda You’ll need to do that with js. With some quick CSS changes, it looks like this [image: 1690796279348-d619844f-fbfe-4cf1-a283-6b7364f6bf18-image.png] The colour choice is still really hard on the eye, but at least you can now read the text

    @Panda you’d be surprised. If you consider that you’d need to use the API to be able to populate a WordPress widget for example (which in turn would of course be PHP), taking this route is still immensely popular.

    @Panda category is for a category in its own, so for example, “fruit” whereas categories is the page that contains all categories as a list.

    @dave1904 that’s a really good point actually. I know it was there previously on Persona, but you’re right - no such function exists on harmony. However, putting something in place to mimick the behaviour of Persona won’t be hard from the js standpoint, although I wonder if perhaps we should ask the NodeBB developers is this feature was overlooked?

    @phenomlab Seems to be better with some scaling fix for redis on redis.conf. I haven’t seen the message yet since the changes I made # I increase it to the value of /proc/sys/net/core/somaxconn tcp-backlog 4096 # I'm uncommenting because it can slow down Redis. Uncommented by default !!!!!!!!!!!!!!!!!!! #save 900 1 #save 300 10 #save 60 10000 If you have other Redis optimizations. I take all your advice https://severalnines.com/blog/performance-tuning-redis/
