When a post is published, any existing automatic map is deleted and re-created – with the default size. Any changes you made are deleted.
If you want to permanently change the size of the automatic map, you can use width=”100%” and height=”300″ in the shortcode.
I don’t see Paris in that map, so it seems like your custom fields are not configured properly, or not working for some reason.
Please check that you’ve done the following:
– you have the ‘directions’ field mapped to ‘address’ in the MapPress settings
– you’ve updated the ‘directions’ custom field – not the map marker – to ‘Paris’ before publishing
I think it will be easier from here if you email me a login using the contact form. That way I can see what you’re doing and give you more detailed guidance.
