Our community was built using Flarum. Now it's using PeerBoard as the platform.
When we were using Flarum, after setting it up, we realized that Flarum adds the site's name at the end of meta titles in search results on Google and other search engines.
It's a huge issue since search engines show a limited number of characters in the title in the results. After that limit, the titles look broken, which is not good for CTA.

I looked for solutions but couldn't find anything. Finally, I came across a professional Flarum developer who developed an extension on my request to fix this issue.
Follow the installation steps given on the extension page.
Upon installation, purge cache and go to your forum's Administration section.
There you will find No Meta Title in the sidebar. Click on it and enable it.

Done! It doesn't require any further configuration.
