    @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.

    @kadir-ay-0 marking as resolved based on https://community.nodebb.org/topic/17109/manual-build-a-night-mode-for-harmony/5 Please do not raise requests in two places - here and the NodeBB forums. All this does is create unnecessary load for both parties.

    @DownPW Yes, it is. It’s set far too low meaning other elements with a higher preference will sit over the top of it.

    @Panda You should be able to expose the CSS for these using F12 to get into console [image: 1686833368846-3591518c-e3a3-4ada-a43c-6b32a5e0359c-image.png] [image: 1686833399483-a2b8ed46-4157-4ff2-85f0-576543380107-image.png] That should then expose the element once selected [image: 1686833431032-89d9c545-a47a-40d1-98f4-80cf3b958e8f-image.png] Here’s the below CSS you need based on the screenshot provided. .composer .formatting-bar .formatting-group li[data-format="picture-o"], .composer .formatting-bar .formatting-group li[data-format="spoiler"] { display: none; }

    @cagatay you’ll need to define this in the body tag (or another element if you want greater or more granular targets) - for example body { font-family: "Poppins"; font-size: 16px; } Essentially, you use the font-size CSS directive.
