Hi Boaz,
I have tried changing my 404 page setting in layout.
Regardless of which page I choose as the404 page in layout:
– If I directly type in the url of the layout defined 404 page, eg. simplymeditate.org/404-page, it looks OK.
– But if I reach the same 404 page through an incorrect url eg. simplymeditate.org/xxx, I see the enlarged h1 line.
This happens equally on my desktop and on my smartphone.
The problem seems to occur ONLY when a user reaches the 404 defined page through an incorrect url.
Hope that helps.
Jonathan
