I hope this is in the right area but I'll apologize if it is not in advance. I'd like to know if anyone can explain what 'Clear Cached Data' is and what it does for a site?

Drupal caches content for faster presentation to anonymous visitors. To clear the cache, you can click the button at the bottom of the page at admin/settings/performance.

Drupal caching can be confusing for developers in development environment, so usually you need to clear your cache in order to make most of your changes to happen during the development. Like while overriding theme related hooks, usually you need to clear your cache. May this post clear you the things more:

So its useful to clear the cache every so often? I'm having an issue in my site, listed here: http://drupal.org/node/446514

Can't seem to get any help. I don't think my site's cache has ever been cleared, I thought to get more background info as to what it means before I hit the button. Thanks for the response and the link, I appreciate it.

You can clear your cache , as a poster above mentioned that Drupal caches content for faster presentation, so there will be no harm clearing the cache. However its not necessary that the problem that you are having will definitely be solved by clearing the cache, it can be and it can not be. But you can try.
