The client is using different forms for each language version of a page, embedded via shortcodes from the Spotler/Mailplus plugin. The Dutch version of the form is overriding key parameters in the form action, affecting its submission.
Solution:
We recommend the following steps to address the issue:
1. Ensure that each language version of the page uses the correct form shortcode. Add them manually if necessary. 2. If preserving URL arguments through WPML settings does not resolve the issue, consider using custom code to maintain the correct form settings upon submission. 3. As a backup, implement a JavaScript snippet to modify the form action after the page loads. 4. If the problem persists, consider switching to a different form plugin that is more compatible with WPML.

If these solutions do not apply to your case, or if they seem outdated, please open a new support ticket. We also highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix, and confirming that you have installed the latest versions of themes and plugins.
