Woocommerce variations

Hi,

I’m having a product with a lot off variations but Woocommerce can’t handle more than 30 variations, as off number 31 i’m getting the notice that my product is out off stock.

It’s a product with 19 options and then you can choose another 3 options for them all.

Is there a way I can fix this. Changing the ‘max_input_vars’ doesn’t seem to help for me.

Thanks in advance for your reply.
