Sites mixed up

Hi. I have two totally different websites: http://stefantsov.com and http://dima.stefantsov.com.

Installed your pagespeed insights, set them up for different google projects with different api keys. But even before I had a chance to set API key for my second site, it was giving message “can’t change options while check is running”.

When check is running on one site, other have to wait.

This is probably some kind of broad cookie issue, do you think you can fix it?

Thanks.
