[Plugin: Visitor Maps and Who's Online] Visitor Maps Blank Page

Hello,

I have been successfully using the Visitor Maps plugin for several months. It is currently not working and I am unable to find the source of this issue.

If I launch “http://www.infostruction.com/?wo_map_console=1” from my website it loads a blank page. The app returns an HTTP 200 when requesting, but no data is contained on the page, only simple HTML.

Do you know anything that might cause this? Can I reinstall over the existing plugin without overwriting my visitor data?

Thanks,
Matthew
