Wrong user being logged in
We're running Vanilla Version 220.127.116.11 and recently we noticed when we log in sometimes we're logged in as a completely different user (not the user we logged in with). And we've heard from other users that when they log in they are also being logged in as the wrong user. Have anyone else run into this issue?
We tried to upgrade to the latest version of Vanilla thinking that might help, following the official instructions here http://vanillaforums.org/docs/installation-upgrade but that completely deletes all the content / discussions / comments on the website!
Any ideas what we can do?
