Question

My website http://www.e-sports.tv.br/ is flashing a black screen when it finished loading. I don't know how to solve this, but the Developer Console returned these errors:

Can someone help me figure this out?

Answer 1

I got similar errors. After trying a lot with dead-ends (crossdomain.xml, etc.) I finally found that the Google Publisher Toolbar was causing the errors. It is an error that will not display in the browser of your visitors, only in yours. If you want/need to fix it anyways, remove your domain in the Publisher Toolbar options or disable the Publisher Toolbar completely.
