Background of the issue:
On the translation management page, WPML detected a new website. This is wrong, I was debugging something on dev.dutchchems.nl but now removed that debugging site. So I press, 'yes this is only a copy'.
Symptoms:
The pop-up message keeps appearing and doesn't go away, and my WPML doesn't work anymore. I can't translate new content.
Questions:
How can I stop the pop-up message from appearing?
