I have JEvents 3.4.9 installed on my site and Joomla is showing an update is available to 3.4.9_1.
When I update I get a success message to say the update has been installed. But then when I return to the admin it still shows the update is available. Cache was cleared but still showing update available.
Perhaps update must be calling in the older update package or is not notifying Joomla the correct version.
