That URL should be:
http://freeknowledge.dyndns.org/enwiki/index.php/Remote_control_frequencies
In the "Remote control frequencies" article, we can see it's using a
template, specifically [[Template:Infobox musical artist]] to
display the musical artists background info. It's this template that seems to be
playing up.
So therefore we go to
http://freeknowledge.dyndns.org/enwiki/index.php/Template:Infobox_musical_a… ; and we
can see there that
the example artist entry ("The Five Heartbeats") is also displaying wrong.
For some reason it's escaping the <td><tr> as
<td><tr> on your wiki when they're used in Parser
Functions, whereas it's
treating them as table tags on the Wikipedia.
From here:
http://meta.wikimedia.org/wiki/Parser_functions#Tables the only difference mentioned that
I can see is that the Wikipedia
has $wgUseTidy turned on, where as probably you
don't. Maybe try setting $wgUseTidy=true; in your LocalSettings.php.
If that doesn't work, someone else may have some suggestions.
All the best,
Nick.
