The below article covers clearing your cache in WordPress and Joomla CMS.
System caching is primarily effective when the database and the content of your CMS application are both located on a single server (Normally found on a VPS or dedicated server). Using caching in the shared environment can have an adverse effect in that it slows the performance of the site rather than speeding it up.
This guide will cover the two most popular CMS systems Joomla and WordPress, if you use a different CMS system please refer to the support guides for your chosen provider.
