 * Hi,
 * I’ve added Ready commerce without problems, but now I’ve this error in few others
   plugins
    “Fatal error: Call to undefined function importClass() in /XXX/wp-content/
   plugins/ready-ecommerce/ecommerce.php on line 14”
 * For example, in nextGEN gallery, when I click on “edit thumb”, it opens a “pop
   in” and have this error.
 * Is it link to the plugin ?
 * Thanks

 * Hello.
    We will try to fix this problem in next release, on this or next week.
   For now you can try to do next: 1. Open file /XXX/wp-content/plugins/ready-ecommerce/
   ecommerce.php in any text editor 2. Replace line: require_once(‘functions.php’);
   with this one: require_once(dirname(__FILE__). DIRECTORY_SEPARATOR. ‘functions.
   php’);
 * Regards,
    Alexey.
