How can I see the exact version of my Joomla 1.5?

The version of your Joomla 1.5 can be seen at the top right corner of your Joomla admin area.

The other place where you can see your Joomla 1.5 version is the version.php file, located in your Joomla 1.5 folder:

libraries/joomla/version.php

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.
