As of this writing, the final version of Joomla 1.6 isn’t out, so the version number displayed here, version 1.6.0, is not entirely correct. I’m running Joomla 1.6.0, but also some version of the beta software, which is not reflected in the footer.
How do I find out which version of Joomla I’m running?
Go to the Site menu, then pick System Information. (This is the same information previously located under Help – System Info in Joomla 1.5.)
Under the System Information tab (yes, that’s System Information twice in a row), you will find the Joomla version of this particular website. Look in the region I’ve marked with the orange box.
In this case, my site is running Joomla 1.6.0 Beta 14.
Because it’s likely that “Version 1.6.0” will show in the footer for the beta versions of Joomla as well as the release candidate, if you see a site running Joomla 1.6.0, you may want to double check the version in the System Information to make sure the site is running the stable version of Joomla. (Joomla 1.6.0 stable is not available as of this writing.)
