 * The cache preload feature simply isn’t working for me at all – it gets stuck 
   forever at caching 100-200 posts, although it doesn’t actually cache anything
   at all. I’m also getting the following error in my logs:
 * PHP Fatal error: Call to undefined function: esc_html() in [URL removed]/english/
   wp-content/plugins/wp-super-cache/wp-cache.php on line 1098
 * My posts are cached in the normal fashion, however.

 * Ooer, just had a thought. If you had the plugin running in half-on mode it’s 
   a bad idea removing those bots. They’ll have to stay I’m afraid.

 * Hi again Donncha,
 * I tried another cache preload, but with the same results as last time – and after
   checking, no PHP errors either. So I don’t have any clue as to why it isn’t working
   I’m afraid.
 * Anyway, the bot preload method is working well. 🙂
