I have successfully used the plug in for a number of months now, thank you very much.
However, now when I add a new location, I am getting an error message “WordPress database error: [Unknown column ‘location_author’ in ‘field list’]”
Please can you advise?
That means your plugin is not activated and installed properly that's why you are facing this issue. Please deactivate the plugin and again reactivate it your issue will be resolved.
