When I look in developer tools, I get a lot of errors on page load.
"The requested URL /attachments/bbq-larver-jpg.132726/ was not found on this server."
And when I look at the image itself it have this path:
/forums/attachments/bbq-larver-jpg.132726/
I would assume that as everything is based on "forums" in our case, the relative path in the error should be OK. But maybe not.
