markers on http://icdsoft.com

I have recently opened a hosting with http://icdsoft.com

I've got Drupal up and running with no problems. However the gmap markers don't want appear. To test this isn't some kind of fluke I've used the same modules on a local install and everything works as expected.

I'm unsure where to go from here. Is there some of kind of debugging I can you through or do I just need to move hosts?

Any ideas would be appreciated
