Hello, @Thomas,
Thanks for the reply.
Have you tried to disable 3rd party plugins?
We’ve disabled CartFlows plugin and the sticky header works fine now. Please clear the cache and check.
We do not give a guaranty for full theme compatibility with all existing 3rd party plugins. Sometimes, not always, you need additionally customize the theme or plugin to make them work together. Unfortunately, it’s not possible for the author to make the theme compatible with all the existing plugins and additional customization is outside the scope of our basic support.
You can try to contact support of CartFlows plugins or change the sticky header type or disable the sticky header.
Regards
