suhosin causes blank page in 0.9.6.x and earlier

    Symptom:
    Installing MODX on a Linux server, running PHP5 and Latest MySQL.
    Hosting Provider is running Plesk.

    I copy all the files, copy the database. Everything as usual.

    After going to the screen, I get a blank page (no content).

    Checked everything:
    - Database is ok
    - Files are ok
    - File permissions are ok
    - Changed the index.php first lines: Added phpinfo(); function. Works ok.
    Very strange.

    My guess now is:
    Provider has suhosin security enabled.
    Value for suhosin.executor.disable_eval is On.
    This disables eval function in PHP.
    Modx needs Eval function.

    Provider is now switching it to Off.

    Since I saw no reference to my problem/symptom/suggested solution, I posted this topic.

      Yes, that’s it !!!

      If you encounter this problem:
      1) Do a phpinfo();
      2) Search for suhosin.....disable_eval
      3) If the value is "On", NOT Good !!!
      Call your provider and tell him not to be so $%^#$%#$ paranoia wink
      and switch it to Off.

        Hey, I’ve got the same problem: I installed MODx 0.9.6.1 on the server, set the file rights but if I click on "install now" I get a blank page (only doctype definition). On Firefox 1 I get this: "<b>Warning</b>: session_start() [<a href=’function.session-start’>function.session-start</a>]: open(/home/vhosts/5000144480/alten-wg-pinnow.de/tmp/sess_958fec6adbcb6e43555ee50bf829f374, O_RDWR) failed: No such file or directory (2) in <b>/home/vhosts/5000144480/alten-wg-pinnow.de/htdocs/install/index.php</b> on line <b>10</b>
        "
        <html><head><title>Loading...</title><script>window.location.href=’http://alten-wg-pinnow.de/install/index.php?action=language’;</script></head><body></body></html>
        I already installed MODx on my localhost with the same server software and it works perfectly =/.
        In the phpinfo() function (http://www.alten-wg-pinnow.de/phpinfo.php) I couldn’t find any suhosin information! The only issue with eval I found is this:
        assert.quiet_eval 0 0.
        hm??

        Server information:
        # Apache/2.2.4 (Unix)
        # mod_ssl/2.2.4
        # OpenSSL/0.9.6j
        # PHP/5.2.4
        # MySQL (but I didn’t come so far)

        concerning page: http://www.alten-wg-pinnow.de

        Please help me!!!

        greetings

          Your PHP config is incorrect with regard to sessions. MODx requires that you have a functioning session configuration.

              Like you can see here (http://www.alten-wg-pinnow.de/phpinfo.php#module_session) sessions are enabled, generally, but I don’t know if there is any special entry which has to be activated (e.g. session.auto_start huh). Furthermore, the /tmp-Folder is the standard folder for sessions in the php ini.

              Please help sad!!!

                Yes man, you are my heroes!!! grin It really works. I never worked with sessions before. I just created a new folder for the session id (/tmp) and give it 777 and it works... *jumping around in a circle

                Thank you

                    Are you sure that the install folder was uploaded correctly?
