While installing multi-site on a shared hosting with hostgator I hit a snag:
Found this fix that actually worked!
Thought I'd share for others:
When a user creates wildcard sub domain in their cpanel using the * symbol, a new entry is also created called webdisk*. this breaks * wildcard sub domain.
Remove the A record for webdisk*
Until I removed the a record for webdisk*
I was receiving errors!
Hopefully this will help someone else!
