senthil.r Posted September 20, 2014 Share Posted September 20, 2014 Hi, I am new to Prestashop, I am using the Prestashop 1.5.4.1 version. This version is not compatible with Responsive, so I would like to upgrade it to latest version. For the upgrade I am using a module '1-Click Upgrade - AutoUpgrade Module'. The upgrading throws a below error. "Premature end of script headers: ajax-upgradetab.php, referer: http://subdomain.maindomain.com/admin1096/index.php?controller=AdminSelfUpgrade&conf=6&token=eb5bd0a7db628d689830adbc39bbc6c1" I am not sure what cause this error and do not know how to fix it. Please help me. Link to comment Share on other sites More sharing options...
