http://freeknowledge.dyndns.org/index.php/Remote_control_frequencies I see these errors on the right hand side. How can this be fixed?
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_ar... ; 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.
