RBGE Yes, it is. I've tried make a new Thank-you page with a different name but the problem still exists.
My latest thoughts went to the second language (nl), that it may be possible that he try to open the dutch page but also there i can't find anything odd. I've replaced the phar file for the folder downloaden from http://i18n.osticket.com and check if it is all set. Unfortunately also without result..

    ntozier I just noticed that also registered users don't have a redirect to the ticket they opened. I assume tho whole redirection (script i assume) is broken. Do you know where I can find it?

      If you are seeing a blank white page then it's likely a PHP error.
      It sounds like your seeing a 500 error which could be PHP, but more likely is your webserver not being configured properly.

      Are you actually running Apache?

      Are you running anything like mod_security -or- SELinux?

        ntozier Yes, I'm running apache. Php 7 on ubuntu 16.04. I am not running mod_security or SELinux.
        Also yes, I recieve a Error 500 like you can see at the screenshot i've posted earlier.

            Logfiles show lot's of notice in file class.orm.php, but it doesn't make any sense to me. Nothing I could refer a 500 error to. I can upload the whole file if you like?

              ntozier To make it less search work i've let the problem accour, log files in attachment

              archief.zip
              2kB

                The attached files does not appear to work.

                I get
                {"errors":[{"code":500,"title":"Internal server error"}]}
                when i click on it.

                  ntozier Wierd haha, You can try http://nedkom.nl/Archief.zip or Read below.

                    @thijskossen

                    If you read the error:

                    PHP Fatal error: Uncaught Error: Call to a member function getBody() on null in /var/www/osticket/include/plugins/osticket-slack-master/slack.php:

                    It says that the system is trying to call getBody() on null...I'm assuming null is supposed to be a thread entry object or something. Anywho, you should contact the plugin developer for further assistance or just remove the plugin altogether.

                    Cheers.

                      KevinTheJedi Sad i dind't figure that my self haha. I've solved the problem. Thanx both for helping.

                      For the ones wondering what the solution was with the slack plug-in:
                      Get body is supposed to fetch the contents of a thread entry. It was missing 'Issue Details' since I deleted that column.

                          2 years later

                          thijskossen Would like to thank you. More than 2 years from this, I resolved my issue with your aclaration.
                          Thanks a lot!!
