  • Hi there,

    I am trying to get a new MODx site set up - but I get this error:

    FATAL ERROR: MODx Setup cannot continue.

    Make sure your PHP session configuration is valid and working.

    The site is on a VPS server, on which I have another site running perfectly sith the same php.ini file so I have no idea what’s happening.

    PHP is running as a CGI module rather than an Apache module.

    Any help very gratefully received!

    • hi,

      the error speaks about session and you haven’t given us any session params... smiley

      something you could have a look at, the session temp dir. Some configurations need you to create a session dir in you website root dir to store sessions tmp files, mays be it could be the case. If so, without that dir, modx session (well any session) can’t work

      (prefer session use trans sid on 0 too)

      have swing

      • Jim,
        I had the same exact issues. It took me forever to figure out how to fix it. I had just upgraded our PHP version to include PDO support. After doing so, session.auto_start had been set to 0. I have a VDS so I just went in to the WHM and updated the PHP configuration (under advanced settings) and changed session auto start to 1. Then restarted apache and restarted mysql (just in case). The errors went away and I finished the setup with no more issues. Good luck!
        • Hi,

          Sorry to dig this old thread but I have the same session error with the install of modx revolution.
          I have tried the session.autostart = 1 thing but it doesn’t seem to change anything.
          And I really don’t know what the correct session configuration should be... huh

          Thanks for any suggestion...

          My configuration (Local server):

          arch linux
          mysql ..
          modx revo

          "/tmp" is "world writable".

          Session Support enabled
          Registered save handlers files user
          Registered serializer handlers php php_binary

          Sessions info from php_info:

          • huh

            Finally it is working...

            I am not sure what fixed it but still here is what I’ve done:
            I just erased all sessions files in /tmp (wich I already did before), cleared the session cookie for my domain in firefox (which I didn’t do before), went back to the homepage and then to setup... seems to work!

              changed session auto start to 1

              In fact this caused me a white screen of death when I tried to login to the manager (just after installation)...
              • when you are running PLESK and have PHP as "fastCGI" look here for a solution

                • I fixed this problem by creating the "tmp" folder to my root folder. I'm don't know about any other settings of mine, but this one little folder "/tmp" fixed this output.
                  • I had an similar issue when running the update setup. Unfortunately the php user had now write access to the php session directory.
                    chmod -R nginx:nginx /var/lib/php/session/

                    This fixed my problem.
