I have checked all possible implementation. It seem an issue that WP or any other CMS system uses htaccess file or index.php inside root directory. Can be avoided this way due to eCommerce or WP conflict.
When I see there are soem top website using:
[
news.mydomain.de...]
[
blog.mydomain.de...]
[
shop.mydomain.de...]
In this way all functionality can be implemented and avoiding any conflict integration.
Is there any feedback?
