As well as giving you information about the cache files and temporary files on your client sites, Yoursites allows you clear these across multiple sites in one go.
We love every single one of our users, without you YourSites simply couldn't happen! So we would love a review at the Joomla! JED so we can let others know about us too, please take a minute to write a review:

If you feel you have something negative to say, we would implore you to speak to us first, as we really really don't want anyone to be unhappy!
