hey there. getting 404 error with new network about wp-multi-network HOT 2 OPEN

Have you set the document root of portfolio.domain.com to the same path as domain.com website (where Multisite is)?

If your control panel does not allow that, just delete the folder "portfolio" (which is probably the document root) and create a symllink instead (portfolio -> document root of domain.com) or ask your hosting support to create it for you.

e.g.: link -s /home/user/public_html /home/user/public_html/portfolio

from wp-multi-network.

If you are running cPanel and can't change the document root of portfolio subdomain, considering symlinks may be an issue for those less experienced, it may be easier to add portfolio.domain.com as parked/alias domain of domain.com . This will create a new VHost in Apache with the proper document root. Depending on your hosting provider policies, this is only doable if domain.com is the primary domain of your cPanel account.

You may need to add a DNS record for portofolio in domain.com DNS zone by yourself.

It may be either an A entry:

portfolio IN A <same IP as domain.com>

or a CNAME:

portfolio IN CNAME domain.com.

from wp-multi-network.
