Problem:
The client is experiencing issues with the header not remaining sticky and the mobile burger menu button not functioning when the WPML String Translation plugin is active.
Solution:
We conducted tests with various combinations of WPML and String Translation (ST) plugins being active and inactive. We also consulted with colleagues to ensure it wasn't an isolated issue. Here are the steps we recommend:
1. Check if the header issue persists on pages other than the homepage. If the header is sticky on other pages for others but not for you, it might be a cache issue.
2. Ensure there are no duplicated headers (one translated and one not). If there are, try translating the untranslated header or delete it.
3. Disable cache plugins temporarily to see if that resolves the issue.

If these steps do not resolve your problem, or if the solution seems outdated or not applicable to your case, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent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. If issues persist, please open a new support ticket at WPML support forum.
