I have been searching for a solution to my double log-in issue and finally am resorting to the forum. Version wise, everything is up to date, wp3.1, etc.
Here's what's happening.
If a user logs in from their own site (sub.tld.com/login) they are logged into their site and taken to their dashboard. If they then visit the main site, they are not logged in and have to re-log in to have access to the main site.
If they log in on the main site (tld.com/login) they are re-directed after logging in to log in again as it forwards them to their dashboard.
People keep thinking they typed their info wrong since they have to re-log in twice.
We are using Multiple Domains plugin and I do have Single Signon enabled btw.
Thanks in advance for your help!
