Joomla has notified you about a new extension update, you clicked on the Update button and instead of a success message you got the following:
To be able to update the Pro version of this extension via the Joomla updater, you will need enter your Download Key in the settings of the Tassos Framework System Plugin
Error updating COM_INSTALLER_TYPE_TYPE_.
Update path does not exist.And you're wondering what's going on. To troubleshoot this issue, follow the steps below:
Step 1: Verify you're using the correct Download Key
As the error clearly states, to be able to auto-update any Tassos.gr extension you must provide your Download Key. To do so, from the main menu click on Extensions -> Plugins. On the new screen, search for the Tassos Framework System Plugin. Click to edit the plugin and make sure the Download Key entered in the plugin settings matches the Download Key in your Downloads area.
If you're using the correct Download Key procced to the next step.
Step 2: Verify your subscription is not expired
Go to your Subscriptions List page and make sure you have an active subscription for the extension you are trying to update. If your subsccription is active, proceed to the next step. If not, you will need to renew your subscription in order to be able to update the extension.
Step 3: Rebuild Update Sites
Each extension provides a URL where Joomla can check and download updates. There are cases that these URLs are broken or invalid. Hopefuly, Joomla has a Rebuild mechanism which rebuilds these URLs for every installed extension. To do so, go to Extensions -> Manage -> Update Sites and click on the Rebuild button.
After the Rebuild process is completed, try to update the extension once again. If that doesn't help either, proceed to the next step.
Step 4: Clear Joomla Cache
Navigate to System -> Clear Cache and click on the Delete All button as shown in the picture below
Once the Joomla Cache is cleared, try to update the extension once again. If the update fails, proceed to the next step.
Step 5: Verify you're using Tassos Framework v4.2.10+
The validation of the Download Key during update process is handled by the Tassos Framework System Plugin. Since version v4.2.10 has been introduced a better way to handle the Download Key which fixes most of the issues occurred during the update process. To verify the plugin's version, go to Extensions -> Manage, search for the Tassos Framework System Plugin. The version appears in the respective table column in the list as shown in the picture below:
If you're not using v4.2.10+, you will need to download the extension you're trying to update and install it over the older version in order to get the fix. After that, you will be able to update Tassos.gr extensions to future releases without any issues. In case, the plugin is updated and you're still facing update issues, please proceed to the next step.
Step 6: Make sure your server doesn't block the update URLs
If the previous steps couldn't help you figure out what's going wrong with the update process, then is must be a server-side issue. In this case, you should get in touch with your host to make sure they don't block the update URLs for some reason.
Step 7: Contact Support
If you've followed the steps above and still you can't update the extension, please open a support ticket mentioning your Download Key.
