Hello,
Please open this file: ../booking/lib/wpdev-bk-lib.php
find this code:
//$date_format = get_bk_option( 'booking_date_format');
//$time_format = get_bk_option( 'booking_time_format');
if (empty($date_format)) $date_format = "m / d / Y, D";
if (empty($time_format)) $time_format = 'h:i a';
$cr_date = date_i18n($date_format , mysql2date('U',$bk_modification_date));
$cr_time = date_i18n($time_format , mysql2date('U',$bk_modification_date));
then replace it to this code (uncomment 2 first lines):
$date_format = get_bk_option( 'booking_date_format');
$time_format = get_bk_option( 'booking_time_format');
if (empty($date_format)) $date_format = "m / d / Y, D";
if (empty($time_format)) $time_format = 'h:i a';
$cr_date = date_i18n($date_format , mysql2date('U',$bk_modification_date));
$cr_time = date_i18n($time_format , mysql2date('U',$bk_modification_date));
Then you can set the date format for the booking creation dates at the General Booking Settings page in form section.
