Edit order http error 500 with WPML enabled

Hi,

I noticed that when I try to edit an order I get redirected to a HTTP 500 error page. As soon as I disable the WPML plugin the error disappears and I can edit my order normally.

Is this error related to the theme or woocommerce?

Does your theme support WPML? I really need to use WPML for this project.

I have already tried to tweak memory limits of the host system. Nothing changed.

Please let me know how to resolve this issue.

Thanks.
