Multiple Joomla websites with a single memcached server

SiteGround offers its customers the option to enable memcached in their Joomla applications. Information on how to configure Joomla to use memcached can be found in our Joomla memcached tutorial.

However, when you have more than one Joomla instance that use memcached, problems with mixed up sessions may appear.

Fortunately, there is a very simple solution - for each Joomla instance you need to set a unique secret word. You can do this by editing the configuration.php file for each Joomla installation. The exact line you need to edit is:

Make sure you change the secret_word string to a unique value for each Joomla instance on your account. This secret word is used by the Joomla memcached controller to differentiate between the Joomla instances so that their sessions don't get mixed up.

Joomla is a powerful software that is easy to work with once you have the right host to support you. Before you lose any more time with the wrong host, check out the SiteGround Joomla hosting offer.
