Since I updated Domain Mapping a couple of weeks ago we have had tremendous issues with users unable to login and getting stuck in a loop. In order to resolve and allow people back into the main site we temporarily disabled it. STILL no one could log in until we realized they needed to delete their cookies.
After doing this they could get into the system however we don't know how many customers we may have lost to this issue.
We have tried re-activating and have now been greeted with the same problem however our users don't understand they need to delete their cookies and are getting stuck in a login loop.
I think I read somewhere about resetting the SALT keys in the config file? Is this something I can do to force all users to download new cookies and resolve this issue?
Thanks for your help.
