Hi there,
It seems that currently, i cant access your Gmail as i have to go through your security sections as you can see here
https://screencast.com/t/8h95jt4ao.
By the way, i checked on your site and it seems that i hit this error when using locations on your site,
Browser API keys cannot have referer restrictions when used with this API.
And i suspected that you didn't configure your keys correctly, and maybe you can try to reconfigure your key again as follow
https://stackideas.com/docs/easysocial/administrators/configuration/location-services-settings and enable those API services prompted including Google Statics Maps API service.
Please advice
