 * Hello,
 * I’m having these errors after update from 2.4.14(probably) to v2.4.17
 * They occur when I update an existing product.
 * > Notice: Undefined index: _price in /public_html/<root>/wp-content/plugins/ecommerce-
   > product-catalog/includes/product.php on line 329
   > Warning: Cannot modify header information – headers already sent by (output

 * upon saving these errors are displayed, but the changes are still being saved.

 * Thanks in advance

 * Hi,
 * Thanks for the report.
 * It seems that this error appears only for old PHP version.
 * You can now update to 2.4.18. It should fix it for you.
