Not an issue with plugins, domain mapping, etc.
My main superuser cannot log in to sub sites; it gives invalid info;
Yet; if i log in to network (and remove domain mapping) and navigate to subsite, it works,
However i do not have issue with 2ndary SuperAdmin accounts;
When i go to the problematic sites USERS table; I notice my ProblematicUsername has a LOCKED status
When I unlock it, I can access it successfully.
--- Is this LOCKED user a core wp fucntionality? Or is it thememylogin or security issues? How can I globally Unlock my username on all sites, or prevent it being locked?
