We have 2 shops with woocommerce and WPML.
The following problems occur.
From a quantity of approx. 50 articles in the shopping cart the checkout process does not end completely.
The order will be processed, but the shopping cart will remain full.
If we disable the plugins WPML Sticky Links, String Translation and Translation Management everything is ok.
So the problem with these plugins has to be related.
All current plugins are installed.
What can this problem be?
We committed with the site developer that this forum is only for that and we won't mess his development, So, for this kind of questions, you should ask your developer (license owner) to open a ticket in the technical forum.
