media redirects


I’m trying to understand how a vanilla install of the Yii2 advanced application redirects off domain when viewed with mobile device(apple, android).

The site ( is hosted at 1and1.

I’m trying to understand how to establish which component is responsible as well as how that component became faulty.

I’d really appreciate some help.



I’m ashamed to admit that an htaccess file had been written to htdocs and I hadn’t properly considered the cascading nature of this configuration tool as a root cause.

I think it came from a poorly configured wordpress install.

Really enjoying Yii2.
