IT is intended as a widget, not for use in posts. I can see your point, but it is not the intended use of the plug-in.
Same here. Except the memory limit shows as NaN.
I tried with a fresh install, with only CodeStyling Localization installed, and then it works. Install another plugin, not matter which one, and the trouble begins.
It collides with core wp functions:
Fatal error: Cannot redeclare wp_cache_add() in /var/www/htdocs/www.planetkips.nl/wordpress/wp-content/plugins/xcache/object-cache.php on line 12
This function is defined in wp-includes/cache.php.
The wp_cache is documentend here: http://codex.ww.wp.xz.cn/Class_Reference/WP_Object_Cache
Resolved, was a theme problem, not a plugin problem. Sorry
