Hi Rikard,

I have updated the theme to version 4.1.2 and the issue still exists. No change at all.
The error I get can be seen in the attached image.
I have reverted the theme back to the version we were using as there were many styles to do with the header (due to some customisations we made) that needed adjusting with the new version, which were not worth spending time on since updating the theme didn’t resolve the issue anyway.

We are looking to go live on this site very soon, so this is quite a matter of urgency.

If you could help me discover the cause of the conflict, that would be much appreciated.

Kind regards
