Hi all,

Has anyone else encountered this issue
vis Error: Invalid Ajax Data when updating Joomla 2.5.9 or later to Joomla 2.5.14?

It appears to be a conflict/issue in the server configuration?
Any ideas as to exactly what it may be?

Updating Joomla - error invalid AJAX data.

Update: "error invalid AJAX data"
This is a server side issue.
On some servers there is a php.ini directive "disable_functions=eval,gzinflate"

Joomla update (com_joomlaupdate) uses gzinflate as follows:
restore.php: $unzipData = gzinflate( $zipData );
restore.php: $data = gzinflate($data);

To resolve the issue have your hosting provider remove the directive disabling the function gzinflate. The directive should read as follows: "disable_functions=eval"

Once the directive is no longer disabling gzinflate, Joomla Update will work normally without issues.
