My entire site is aligned all the way left

Hi folks. The whole site is like this. For a while actually after I had to migrate my site to a new machine (self hosted). I’m just now getting around to addressing it.

https://tiribulus.net/wordpress/

This site gets very little traffic. It’s a more of a resource that I link things from so it hasn’t been urgent, but I really should fix this. The one and only thing I could find after an hour of searching the web was on this forum and it was closed with no answers.

If anybody knows how to fix this, I sure would be grateful.

Thanks ??
