I activated the Product Per Page plugin for Woocommerce and i have this message:
Notice: Undefined index:
behaviour in /var/www/shop/wp-content/plugins/woocommerce-products-per-page/objects/wppp-dropdown.php on line 30
Notice: Undefined index:
behaviour in /var/www/shop/wp-content/plugins/woocommerce-products-per-page/objects/wppp-dropdown.php on line 32
Wordpress version: 3.9
Woocommerce version: 2.1.7
How to solve this issue?
What theme do you use? I've had an another report on the Wordpress forums with the same notice. This was on the Genesis framework.
I will put out an release (probably) this weekend which will fix this.
Other than that I believe it is unusual to get an notice error on a live website, do you have WP_DEBUG on in your wp-config.php?
Anyhow stay up to date in this topic.
PS. I recommend to open an support topic in the Wordpress forums next time if you need support, I found this by coincidence :).
