first of all: Thank you very much for your amazing work! I am just getting into joomla and everything works out very nice and your module is a great improvement for joomla since there does not seem to be much support for OSM in Joomla at all!
I am using a joomla template from joothemes and I am customizing it a bit. One of the things I've changed is to remove the original Google Maps map and replace it by your Zh OpenStreetMap. This works great, but the module is somehow overlaying the template. I am not a web developer, but maybe there is an easy workaround.
I've also attached two screenshots: One with the original module "OT Maps" and one with your module.
Thank you very much for your amazing support! This solved it for me. Still getting into all this web stuff since I'm usually writing embedded software applications and building hardware so this is all new, but I guess I'm slowly starting to get the hang of it!
