Multisite subdomain link issues

Hi,

I’m having an issue with the links in the subdomains. If I add a link in one of the subdomains, the link ends up being a different one than the one I add. For example if I add https://mydomain.website/sign-up in one of the subsites eg. demo.mydomain.website sub site it ends up being http://demo.mydomain.website/mydomainwebsitesign-up.

Hope I explained it correctly. The same thing happens to the other subdomains. It adds their respective subdomain before the link I hard code in. I’ve tried resetting the permalinks and no luck.

See attached snapshots to see what I mean.

Thanks,

Jaime
