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. 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

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

I hope you can help!!

Thanks :slight_smile:
