So out of the blue today it looks like this extension brought down my entire flarum. Here is what happened.
The website has been working great lately. BUt I visited it one last time right before going to bed tonight and all that was displayed when I visited it was this:
Error booting Flarum: SQLSTATE[HY000] [2002] No such file or directory (SQL: select value, key from settings)
After further investigating and looking at my FLarum Logs I pulled this out:
[2019-01-23 04:19:19] production.ERROR: Error: Call to a member function getAttribute() on null in /var/www/seekadventure.net/vendor/v17development/flarum-seo/src/Mana$

After speaking with @jordanjay29 in the discord room he suggested disabling the SEO plugin based on the above error.
I could not access my site at www.seekadventure.net because it gave the first error just on a white page. But www.sekadventure.net/admin worked and I was able to un-check the SEO plugin and when I refreshed my main page everything started working again.
