I have a WordPress Multisite (Sub-Domains option) with a few of sub-domains already working.
The site is located on a managed hosting with wildcard disabled.
So every time I want to create a sub-domain I'm forced to: a) configure the sub-domain on the hosting panel and b) set it up in WordPress backend
But now I need to create sub-domains on-demand; this involves the activation of the wildcard in the server. My provider can enable this functionality and is waiting for my confirmation.
My question is: can I activate wildcard quietly or I risk of breaking the site or its subdomains?
