The latest update of the wordpress theme I use here on OAM was somewhat buggy.
This means that some pagelinks under the main menu items does’nt show up on smartphones and tablets – eg. the Renderthemes under “MapStyles”. I made a workaround for this problem till the author of the theme provides a fix.
However, you have to empty the page-cache of your browsers to ensure that this fix will work.
So, please empty your browser cache:
