Incorrect setting description and possible unecessary setting
The setting Caching PATH seems to have an outdated description:
This is useful for specifing a PATH for the IP.Board written files (skin_cache, style_emoticons, style_images) when dealing with load balanced/clustered servers. If you enter a PATH, please ensure that it ends with a trailing slash.
Note: This location must have a 'cache' folder. So if you enter /home/path/ then you must have a folder /home/path/cache/
However, caching path is not used for style_emoticons, style_images or any of the other style_ -folders, as you might get the impression of. And since caching path is not used for any other folders or files outside the cache-folder, it looks like it's unnecessary to have it point to the parent folder. (I refer to So if you enter /home/path/ then you must have a folder /home/path/cache/ )
Which leads me to the setting: Caching URL. Is that really a necessary setting then? I can't see you would ever allow someone to link directly to files within the cache-folder? It's only php-files or written debug-files in it anyway.
