You need both the "FEN" and "SetUp" tags in order for this to work.

hmmm the problem must be somewhere else.

the PGN standard requires the SetUp tag to 1, but if FEN is present and SetUp is not there, then pgn4web is tolerant and it assumes as if SetUp = 1.

the following is without the SetUp tag in the input:

[FEN "r2r2k1/5p1n/1pp1b2Q/p1p5/q3P2N/3P3P/1PP3P1/3RR1K1 w - - 0 23"]
23. Nf3! Qb4 24. Re3 Qxb2
25. e5 Qxc2 26. Rf1 Rxd3 27. Ne1 Rxe3 28. Nxc2 Rxe5 29. Qf4 f6 30. Qg3+ Rg5 31.
Qc7 Bxh3 32. Rf2 Rc8 33. Qxb6 Be6 34. Re2

do you have a link to the errored post?

The errored post was missing the "FEN" tag, so I don't think that this is your problem -- there was simply no initial position. I've fixed the post in question, but you can reproduce the "issue" I was seeing if you just remove the "FEN" and "SetUp" tags from my posted version.

No need.

I thought in your post you meant the FEN tag was there but the SetUp was missing.
I did not think anyone would expect a PGN from a non-standard initial position without telling the PGN viewer somehow what the actual initial position might be

Exactly. I just wanted to document the PGN-compliant way of doing so.

Does O-O-O+ work?

Apparently not. I'll fix that.

But this doesn't work as of 19:18 CET on the 10th of January 2011, either. I just patched the latest version of pgn4web for use on OpenChess and will switch over to it shortly, at which time, this _will_ work.

I've switched over. Please let me know if you observe any (new) unwanted PGN behavior.

13. Nc3 Bf5 14. O-O-O+ Kc8 15. Be2 Bg7 *Still not working with O-O-O+? At least for me it doesn't, as clicking on "Be2" in move 15 gets stuck with Black's 13th still highlighted.
