Support » Plugin: Give - Donation Plugin and Fundraising Platform » Warning: session_start(): Cannot find save handler ‘memcache’

  • Resolved djpeanut


    I love this plugin in so many ways, except for the fact that it spits out the following PHP warning before any HTTP output:

    Warning: session_start(): Cannot find save handler 'memcache' - session startup failed in /home/tomsbike/sites/ on line 367

    Has this been reported before? Any idea what the fix might be? I’m on cPanel shared hosting.

    Hi there,

    This is the first I’ve seen of this error. Can you provide us with your system info? Go to “Donations > Settings > System Info” I think this might be related to your environment.

    Also, what host are you on? Occassionally hosts do strange things with PHP Sessions.

    Hey @djpeanut – We’re glad you love our plugin, that’s always good to hear! 🙂 I haven’t seen that particular PHP warning reported as of yet. Doing a quick Google search on it brings up some server specific settings that may need to be updated on your end. In fact, PHP warnings shouldn’t display on a live site but that’s besides the point. It sounds like there’s an issue on your server running PHP sessions.

    Try adding define( 'GIVE_USE_PHP_SESSIONS', false ); to your wp-config.php file within the root WP directory. Then run a few test donations to ensure everything is working properly and the warning no longer displays.

    Let me know how that goes!

    HI @djpeanut did you try implementing the change the Devin suggested? Let us know how that goes.

    Hi Matt,

    I didn’t try Devin’s change but I did spot a suspicious looking php.ini file in my WP root that I didn’t recognise. On opening it I spotted the following lines:

    session.save_handler = memcache
    session.save_path = "tcp://"

    This looked like an attempted exploit and the possible cause of the issue. Deleting said file resolved the problem.

    Very odd!

    Thanks for the follow up with your solution!
