Hello!
I am sorry that you are upset and you have difficulties in setting-up correctly our plugin.
The forum at wpml.org sometimes is overloaded, and you might receive a response with up to 24 hours of delay – depending on the load.
However, we also offer initial support here in the Support Threads for WooCommerce Multilingual – where you can also ask for help, and if you have a ticket in wpml.org to point us to that ticket so that we can prioritize it (if possible).
If you wish for me to help you – please let me know, provide more details about the issue and your wpml.org ticket link and let’s work on the problem.
PLEASE PROVIDE SOLUTION TODAY

I provided you with a solution.
It seems that your theme and one another plugin are not compatible and quite outdated, thus creating the issue with the option “Language as parameter” in WPML > Languages.
