quantity of attributes and product variations limit?

FG WooCommerce:

I am writing you becasue I am unsure if I need to purchase a plugin.PLease refer to my 2 questions below.

1. How many product variations are allowed with Woo Commerce?
My theme support says they are unlimited as far as how many they allow, but I am having a problem crossing the 50 limit when it comes to attributes and variations. They said to ask woocommerce how many you allow.

You may see my problem here:

It displays all the options under the third drop down menu except when on the second drop down menu “extra large” is selected. That is about when I cross the quantity of 50 mark under the variations listed.

2. Where my I find woocommerce support for your basic free plugin?

version 3.6 of wordpress
version 2.0.13 of woo commerce

Best,
Jamie
