Intermittent Unknown login key: a debugging path? (3 posts)

    Hello, I'm dealing with a hard to catch error: some of my users report that when entering one of the sites of the network, they end up with the "Unknown login key" message that I can't reproduce with my own user and password.

    Is there a way to check/debug what's happening?

    I have around 40,000 rows in the domain_mapping_logins table, but what I've seen is that you delete unused logins after 120 seconds. Is this proof that not all operations end up in the database?

    What tricks can you show me/send me?

    Thanks in advance.

    To expand: I tried to write a dump with all variables every time it happens, nothing -unusual- found. I tried extending the 120 seconds to more time just in case it was deleting logins too soon. I tried redirecting to the login page but that gets the user into a redirect loop because he's correctly logged-in.

    I'm wary of deleting the 40K records in the database to start fresh because I don't want to piss off our readers by killing their logins.

    Any recommendation will be very welcome.

    Thanks again,

    I am getting a similar error but am actually able to replicate the results. No fun. I have been able to temporarily fix it by changing the salts in wp-config


    I would like to stop this from happening all together tho... or at least learn why it is happening.
