@JasperVriends looks like I found another bug thanks to the search console.
Google search console started showing certain pages were not loading. I went to the page to investigate and it said:
An error occurred while trying to load this page.
I then went to my main page of my Flarum and that worked fine, and I navigated to the page and the same page worked. For example, if you go here directly it will fail:
https://www.seekadventure.net/d/43-thermarest-neoair-uberlite
But if you go to https://www.seekadventure.net first then look for that same thread and click it then it magically works. Basically, direct links do not work.
Error log here:
