Login to admin area of mapped domain

Hi,
today I purchased your Domain Mapping plugin, installed it as written in your documentation and network-activated it.
My main site is http://denksport-it.de - it's a sub-domain installation.

I want to map my site http://ankauf-militaria.denksport-it.de to http://ankauf-militaria.info.

I works quite well, I added the domain in your plugin and changed the domain in WP Networks -> Sites -> Domain.

But now I can't login to the admin area of http://ankauf-militaria.info. I tried all three settings "domain entered by user", "mapped domain" and "original domain" and neither works. In the error logs I can see a lot of rewrite rules failing, is there any special configuration for nginx needed?

I'd appreciate some help :slight_smile:

Best regards,
Jan
