Hi,

I do my upgrade by downloading the latest version and unzip the newly downloaded file on top of the previous version and ensure I overwrite all files.
Everything is fine.

However on the admin page, I always got the message "A new version of Piwigo is available."
But when I click on "Check for upgrade" or "admin.php?action=check_upgrade", I got "You are running Piwigo latest version."
And when I click on the message "A new version of Piwigo is available." or "/admin.php?page=updates", I got "You are running Piwigo latest version."

I narrow down the issue to the javascript call by the "intro.tpl"

"ws.php?method=pwg.extensions.checkUpdates&format=json"

This return the following json:

{"stat":"ok","result":{"piwigo_need_update":true,"ext_need_update":true}}

As "piwigo_need_update" is set to true, the message "A new version of Piwigo is available." show up.
I did not see any sent header that include the version.

Any hints?
