login intermittent failure

  • I’m looking after a non-profit society website. Members can log in to see additional information.

    Everything works fine but for one oddity. Logging in sometimes doesn’t work first time, but trying again does.

    I’d seen the issue before but when a retry works you assume you made a typo first time, however a member reported the same issue yesterday so I did some testing.

    On further investigation there’s a loop: Login>fail; Login>success; Log out; Login>fail; Login>success; Log out… etc i.e. alternate logins work. Not browser dependent (Edge/Chrome/FFox/Opera current versions).

    And what coders really hate is happening – it’s an intermittent issue: yesterday I had the problem, today I can’t make it fail however hard I try. Nothing has changed since yesterday, not rebooted the PC, not updated WP or any plugins.

    In the circumstances I know it’s a long-shot but any thoughts?

    SWPM: Version 4.0.3
    WP: version: 5.6
    Theme: Twenty Eleven Version 3.6 (with child theme)

    Hi,

    Everything works fine but for one oddity. Logging in sometimes doesn’t work first time, but trying again does.

    Do you have a cache plugin running in the site or your server?

    Thank you

    Cache: yes. Next time I’m logged into the server I’ll see what happens if I suspend that.

    I had another thought though. I’d been focussed on the server side of the problem, I wonder if it could be my PC as I realise I had made a significant change yesterday, moving from Kaspersky internet security to Bitlocker. Security packages do have a habit of looking at web-traffic, blocking malware sites for example, I wonder if that could have been interfering somehow.
