I was also having this issue on Retina mac. The logo was dropping below, outside of the header.
The code below fixed my issue as well:
#logo img.retina { max-width: 95%; }
I had included my two URLs with * for wildcards before and after the URL.
However I did not have a / after the URL before the * That made the difference. Once / was added it works correctly now Sorry for run around.
theme updated. issue still persists.
Regenerated key, replaced key and saved. Was able to briefly see map before it threw the error again.
duplicate theme removed.
should also note this is a fresh wordpress install with no extra plugins.
