Subsite is not being recognized when created from site front-end or by admin

Hello support,

I hope this finds you doing well and having a great day.

I have a multisite network that I'm activating Pro-Sites on.

This is the first time I'm using pro-sites.

I have gone through the setup process backwards and forwards but for some reason the subsites are not resolving. (not having this problem on other networks) e.g. http://demosites.co which has like 15 subsites but not with prosites.

I have activated support access to both sites and I'm doing a full backup on sitetaylor.com

For the life of me I can't figure out what may be setup wrong.

I hope you can help!!

Thanks :slight_smile:
