Fatal error: Call to undefined function date_diff() in /home/domain/public_html/installation/wp-content/plugins/smart-manager-for-wp-e-commerce/smart-manager.php on line 373
Hi,
Sorry for the inconvenience caused.
Would like to update you that in the recent release of Smart Manager we had included the PHP ‘date_diff()’ function and the same is available only from PHP 5.3 onwards.
So, looking at the error message provided by you, it seems that you are using a lower version of PHP on your server (i.e. > v5.3).
Further, request you to kindly have a check with your server administrator and if possible upgrade the PHP version to something greater than v5.3 and then have a recheck with Smart Manager functionality.
P.S. For any further queries or communication request you to kindly mail us the same at ‘[email protected]’.
