Problems when adding products

​Everytime we add a new product, the system shows the following message:

Notice: Undefined index: recurring_id in /home/panamaou/public_html/NACHOVALDERRAMA.COM/admin/model/catalog/product.php on line 272Warning: Cannot modify header information - headers already sent by (output started at /home/panamaou/public_html/NACHOVALDERRAMA.COM/admin/index.php:80) in /home/panamaou/public_html/NACHOVALDERRAMA.COM/system/library/response.php on line 12

We haven't been able to figure out exactly what produces this error.

Please help

Any news?

We had the same issue and tried http://forum.opencart.com/viewtopic.php ... 72#p552685
It worked.
