Hi Siobhan,
thanks a lot for your support!
I know that use a child theme it’s the better and clear option, but for this work i will fix the map code in the code of PHP and CSS. This blog is only for internal use.
At this moment by the plugin generated code i tried to put the map after the “masterhead” section, before the 1st post, but this solution does not like at the end. Was asked me to include the map in the footer or header to have it available in every blog page. If better option is present, I will be happy to evaluate
