All user map just stopped working.

I’ve had the gPress plugin for a month now and it’s great. My community have over 4,000 users, with 100’s of people creating maps of their own location. Those maps work perfectly. I have a sitewide map with all the users showing on it fine. Yesterday the map stopped displaying. I downgraded the plugin and site doesn’t work. The users individual map works fine btw. My site is swapbbm.com Log in using > test | test. The sitewide map is Member Location
Any help would be great. Thanks.
