Due to an issue with Admin Tools 4.0.0.b1 to 4.0.0 inclusive, users of the Professional release must update manually to this new version.
If you are using Admin Tools 4.0.0 or any of its beta / RC pre-release versions you must update manually. Read on for more information.
The Professional version's downloads, including updates, are not free of charge. You need a valid subscription to download them. We implement this check on our site by means of the Download ID you enter in our component.
However, Joomla cannot directly read the download ID from the component's configuration. It has to be placed in a special format in the database. Every time you visit Admin Tools' control panel page we check if the Download ID is in the database in the correct format and set it if missing.
Due to a bug in Admin Tools 4.0.0 and its preceding Beta and Release Candidate versions a blank Download ID was put in Joomla's database. This means that Joomla tries to use an invalid URL to download the update package for Admin Tools, making it impossible to update automatically.
The ONLY way to fix it is to perform a manual update. There are two methods to update manually: using install from URL or using the simpler upload and install method.
VERY IMPORTANT: No matter which method you use, do NOT uninstall Admin Tools before updating it. Doing so will cause all of your settings and data to be deleted.
This is the same process Joomla follows internally when you update Admin Tools. Therefore it's usually the safest bet to installing / manually updating our extension.
This method fails on some servers because they don't allow Joomla to download files directly. If you are on such a server you couldn't use Joomla's one-click extensions update anyway so you'll have to use the Upload and Install method instead.
If you are using a computer running the Mac OS X operating system and use the Safari web browser the first step will result in the ZIP file being extracted instead of being downloaded. You can either change that option in Safari or simply use another browser such as Mozilla Firefox or Google Chrome to avoid this issue altogether.
For any other issue please consult our very thorough extension installation troubleshooting guide (it applies to all components, even components which are not our own). Alternatively, use the fully manual installation method described in our documentation.
In order to be most efficient in providing support we chose to publish this page with all the information we can provide on the subject. We want everyone affected to be able to read it and apply the mitigation described. Any further extension installation issues you may face can be solved by reading the extension installation troubleshooting guide according to our ten years of experience. If you have an issue after installing the update please file a new ticket as it doesn't pertain to the update issue.
