@fffddd-dfeeedd No, most likely they will not affect Google rankings. Any external links from NodeBB are automatically nofollow'd, and those bugs you've pointed out don't affect ranking of the page itself.
So many bugs with the plugins
There are lots of bugs the plugins i installed one and it gets uninstalled after restart or I try to delete a theme and when I restart it comes back
UPDATE: I now installed Gravatar plugin and then Q&A question and answer, then restarted NodeBB and the gravatar one got uninstalled except the Q&A one......
UPDATE 2: Sometimes it throws an alert with npm no write permissions.
How do I fix this annoying issue?
Using the latest NodeBB version.
