Hello,
I cannot find this plugin reported as compatible in our compatible WooCommerce plugins here: https://wpml.org/documentation/woocommerce-extensions-compatibility/
If you wish, I could escalate this issue to our compatibility team, and they can attempt to contact the plugin author – in order to make that plugin compatible.

Hello again,
I tested the scenario that you outlined here.

Unfortunately, I cannot reproduce it with all the latest versions of the mentioned plugins that I have.

Would you care to elaborate further?

It would be also very nice if you would create a ticket in our forum at wpml.org – so that we could investigate more in-depth your issue. Perhaps it is something related to the versions that you are using? Or some compatibility issue with other plugin, or your theme.

I am glad that my answer was helpful to you.
If you wish, you can read more about the subject here:

And in the linked articles where they inspect the performance when xdebug is enabled:

Disabling the extension would make your server even faster.

Hello and thank you for contacting us.
It is recommended that you disable xdebug php extension when running a production environment of WooCommerce or WooCommerce Multiligual for that matter.
Running xdebug can cause severe performance issues, and as it seems in your case – the maimum nesting level of 100 being reached.
You can read more here: http://stackoverflow.com/questions/17488505/php-error-maximum-function-nesting-level-of-100-reached-aborting

You can fix it by either disabling xdeubg, or rising the debug.max_nesting_level in your php.ini or xdebug.ini – if you need that extension.

Please do note to use xdebug only on a testing/development server, because it can cost a good deal of performance.

Hello,
Could you please provide more information about the issue that you are experiencing?

Please also check if you have the latest versions of WPML and WooCommerce Multilingual.

In some cases – where a compatibility issue may be the problem – switching all non WooCommerce and WPML plugins off and selecting a theme like Twenty Sixteen, may help to determine where the problem is.
