I'm so, so sorry to have to do this, ugh.
I've turned custom comment pages back on in my journal, guys, because I cannot handle the changes LJ made to comments on non-custom comment pages. It's not ideal, it's not something I want, but I can't read the other ones, and at least I can handle reading my own default layout. So until they either change it back or make it better somehow, I'll be looking like this.
