I have a similar problem. I think it may be a conflict with a event-creation plugin I use. I can’t get rid of this plugin because my site is based on it. In each event, I specify the address/location and the plugin maps all the events on a combined map, based on location or time. Very nifty. I would like to add a map to a post, but none of the 6 mapping plugins work, or work with strange display issues that make them unusable. Is there a way to eliminate such a conflict (while keeping my event-scheduling plugin) so that I can get flexible map to work?
Thanks,
Rex
