That is strange… I see the WP Geo script files on that post in the source header:
<script type='text/javascript' src='https://maps.google.com/maps?file=api&v=2&hl=sv&key=ABQIAAAAZRz-mWOhyCjZXN-bvCD2eBQ0ALTbUHpwTTD3XlgfnTmC21kYOxSEh-umDx9-IVzgwJBgNIlYyFvNlA&sensor=false&ver=2'></script>
<script type='text/javascript' src='https://blogg.attefall.se/wp-content/plugins/wp-geo/js/tooltip.js?ver=1.0'></script>
<script type='text/javascript' src='https://blogg.attefall.se/wp-content/plugins/wp-geo/js/wp-geo.js?ver=1.0'></script>
But on the fotoalbum page those scripts are missing. Without those, there can be no map. Can you please test putting the Mashup Map shortcode in that post for me? Just to see if (with whatever strange result with TWO maps alongside each other) it is working there…
