Setting up a demo site for a client, trying to add their locations using your plugin. I got them all set up and then when adding the 4th location I got a "Fatal PHP Error, Cannot use string offset as an array in".
A link (with error) is available here.
Deleting and reapplying.
Deleting the options within phpmyadmin
A combination of the above
Nothing fixed it, same exact error every time.
