I find myself confused...
Having (not enough) experience in creating custom loops, and the functionality your plugin provides is almost exactly what I'm looking for, can you tell me why your code works offline but not online?
It's quite happily ticking away on Firefox 4 as part of my testing rig; but now the code is in
ctspro.co.uk it refuses to work.
I have inserted
<?php random_post_box(); ?> into an include that in turn governs what's in my sidebars.
I have pasted the code into the code-block that governs what happens when there is no dynamic sidebar; still no dice.
I have tried attaching the shortcode
[random-post-box] into a text widget (something which I would like to suggest as a feature BTW), but again no joy.
I have also deactivated a plugin that I thought could be conflicting, but that hasn't worked either...
