This plugin hasnt been tested with the latest 3 major releases of WordPress. It may no longer be maintained or supported and may have compatibility issues when used with more recent versions of WordPress.
Chris has worked with me closely to get this map up and running on our site. This is our company's second purchase of this map, but the first time we needed some support in getting it going. Support is exceptionally responsive and patient, I cannot say enough good things about this company.
The map itself is perfect for our needs; fully customizable including the option to directly edit the code if needed.
Awesome plugin and supporting documentation. Great user support. Simplemaps.com has a whole host of additional resources applicable to this plugin.
Using HTML, CSS, and JS/jQuery allows wider customization over software-generated map programs that utilize other methods of visualization, interaction, and data interpretation. For instance, embedding images within hover elements/tooltips is a breeze with this plugin.
Great work, simplemaps!
