Hey Dariusz,
thanks for reaching out and for all the links – don’t worry, we appreciate your help ??
We’re sorry you’re having issues with our plugin and we’ll gladly help.
However, I suggest we move this discussion in another support topic as it seems to me it is not so related to previous issues already mentioned here, although the message you got is the same. Can you please create a new topic? Thanks
In the meanwhile we’ll test our plugin with WPML and check what’s going on. It would be also helpful, if you’d provide the version of your WordPress and WPML plugin.
Take care & have a nice holiday ??
Mateja
