WooCommerce - variable products for all atributes

I am developing an online sales site for a client. I work on my website online hosting by Godaddy.

I have install the WooCommerce plugin.

I want to add variable products. I already enter the attributes I need. When the time comes to convert it's attributes in real variables, using the button create variations for all attributes 95% of the time it does not execute anything. Nothing append. I don't know what to do.

The button for creating one variation work fine actually. I don't want to enter 312 variations (approximately) one by one. I can make many mistake.

I see in a forum that deactivated all my plugin (except WooCommerce) work for minimum 2 persons. For me it's do not work.

How can I make my button works all the time?

• Version of WordPress : 4.3.1
• Version of WooCommerce: 2.4.10

Thank you!
