I came across this one on my own site and thought I'd share the fix.
I'm hosting plugins on my site using Self Hosted Plugins. That same site has a couple of those plugins activated (for demos etc.). When Self Hosted Plugins rendered the plugin description page, it filtered the content through do_shortcode. It tried to expand all of my example shortcodes.
To fix this, I added the following to my theme's functions.php file. The code simply removes the do_shortcode filter on the_content:
add_action( 'pre_get_posts', 'topquark_massage_spoof',99 );
function topquark_massage_spoof(){
// I don't want shortcodes to get expanded on this page (so I can put shortcodes in the readme on a site)
// that has the plugins activated
if (defined('SHP_SPOOFED_PLUGIN_PAGE')){
remove_filter('the_content','do_shortcode',11);
}
}
Cheers
