Cannot Update to 1.2.3

When trying to update it shows the following:

Step Status

Downloading Package Success

Extracting Package In Progress



I will then sit there for the rest of time (or 6 hours is the longest I have left it open).



In the error log shows:

[08-Jan-2016 14:06:04 America/Phoenix] PHP Fatal error: Class ‘ZipArchive’ not found in /home/manageit/public_html/mautic/app/bundles/CoreBundle/Controller/AjaxController.php on line 393



How do I fix this?

Your server doesn’t have the zip extension built in which is required in order for mautic to extract the update package. If this is a VPS, see http://php.net/manual/en/zip.installation.php. If on a shared server, you will need to contact the host.

Thanks!
