LJ bio HTML woes, anyone?

Welp, I updated my profile text and apparently broke my LJ profile in the process. I'm using the same raw text there as on my DW profile where it's working fine (though obviously I've changed DW username coding where necessary), and there's only a couple of new bits of HTML there, but now the whole thing is refusing to display properly. Is anyone else having trouble with HTML in LJ bios? I don't want to bother Support if it's just one of those transient bugs, or I've made some really obvious embarrassing coding mistake:

( Code is under here, but with gaps inserted so the links won't try to link within this post. )

Here's how it's currently displaying on my LJ profile - maybe the error code is indicative of something: http://cloudsinvenice.livejournal.com/profile
