If you are using Joomla! 1.7 or 2.5 and Akeeba Backup Professional, please read our release announcement. As clearly stated in there in bold, italicised, underlined, capital letters you should not use Joomla!'s extension update to update Akeeba Backup. It will not work and will result in an error. Instead, please either use Live Update (the UPDATE FOUND icon in Akeeba Backup's control panel page) or download and install the new version like any other component, without uninstalling the existing version. Please note that Live Update may need up to 24 hours since a new release is published before it "sees" it and allows you to update to it. This is a limitation imposed by caching and the nature of the CDN which powers its update streams.
If updating Akeeba Backup fails and you no longer have access to your site's back-end you have to remove the following files or directories:
administrator/components/com_akeeba/akeeba
administrator/modules/mod_akadmin
plugins/system/srp.php (Joomla! 1.5, Professional release only)
plugins/system/plg_srp.php (Joomla! 2.5, Professional release only)
This should allow you to get back to your site's administrator area and re-install Akeeba Backup. If this still doesn't work and you get an error message during installation, please refer to our
installation troubleshooting instructions.
If this still doesn't help, please take a look at your Joomla! and PHP versions. If you have Joomla! 1.6, or if your PHP version is less than 5.2.7, you will have to use the (unsupported) Akeeba Backup 3.2.7 release, available from our download area. Please note that this version is not supported and should only be used as a temporary measure until you upgrade Joomla! or your PHP version. We regret to inform you that these Joomla! and PHP versions are end-of-life for many months (or even years) and we can no longer support them.
