I think I've turned a relatively simple task into a nightmare, and after days of trying to find answers on here and elsewhere, really could use some help.
Briefly, I was developing 3 separate WP website installs with 3 MySQL databases (www.example.com, major.example.com and minor.example.com). Just before launch I realized that users who register on a domain are not recognized on another. This meant I would have a massive fragmentation of user data.
After a lot of searching on here and discussion with Godaddy support, I decided to merge the 3 installs to Multisite on the understanding that the userbase would become shared across domains, thus resolving the fragmentation issue.
Unfortunately, it appears I have the exact same problem with Multisite!
To my chagrin, I have just discovered that there was an alternative solution:
Merging the 3 databases into one,
and installing WP-Orphange Plugin.
My question is this:
Can I use the above solution with Multisite now, or do I need to revert to 3 individual installs and then apply the fix?
I would be ever so grateful for a response as this has become a real nightmare and I desperately want to get my websites up after 3 months development.
Thank you :-)
