Hello and thank you for contacting us about your update issue.
Before we begin please understand that extension updates are discovered, downloaded and installed by Joomla itself, using code that's under the absolute and total control of the Joomla project. Akeeba Ltd can not and does not have any influence on that code. In simple terms, your issue is a Joomla bug which is NOT influenced by anything we have done, currently do or can ever do.
Workaround
IMPORTANT! Please follow all of these steps in the exact order provided below, without skipping any one of them
even if you think it is unnecessary. Each step and the order we tell you to follow is the result of dozens of hours poring over Joomla's code, understanding how it works and figuring out the shortest workaround to many weird things Joomla does.
For each one of your sites:
- Go to the backend of your site
- Go to our software's main page e.g. click on Components and then on Akeeba Backup or Admin Tools or Akeeba Ticket System Professional depending on which of our software you have.
- Click on Options in the top right corner. This opens Joomla's com_config component showing the settings for our software.
- Clear your Download ID.
- Click on Save & Close.
- Click on Options in the top right corner again.
- Enter your Download ID.
- Click on Save & Close.
- If you have more than one Professional version of our software installed repeat the process from the beginning until here for each one of: Akeeba Backup Professional, Admin Tools Professional, Akeeba Ticket System Professional.
- Go to Extensions, Manage, Update.
- Click on Clear Cache.
- Go to System, Clear Cache
- From the dropdown select Administrator
- Click on Clear All even if the list is empty. Joomla has a hidden query cache which screws up updates if you don't clear it.
- Go to Extensions, Manage, Update.
- Click on Clear Cache again.
- Click on Find Updates.
