benteil Posted November 25, 2010 Share Posted November 25, 2010 Hi all, same problem for me. Anyone ??? Link to comment Share on other sites More sharing options...
rocky Posted November 26, 2010 Share Posted November 26, 2010 Have you mixed and matched files from different versions of PrestaShop? PrestaShop v1.3 has an isString($data) function at the bottom of classes/Validate.php, but PrestaShop v1.2.5 doesn't. Make sure the function exists.
