  • Moving forum to new server - blank screen / 403 / 500

    Hi!

    I recently had to move one of my forums (3.6.8) to a new server.

    After a few troubles I got the database over okay (afaics), the files themselves weren't a problem either.

    But now I get this error message:

    500 - Internal Server Error

    This is a temporary server error.

    Please try to reload the webpage later.

    If you are the webmaster of this site please log in to Cpanel and check the Error Logs. You will find the exact reason for this error there.
    Common reasons for this error are:
    • Incorrect file/directory permissions: Above 755. In order files to be processed by the webserver, their permissions have to be equal or below 755. You can update file permissions with a FTP client or through cPanel's File Manager.
    • Incorrect Apache directives inside .htaccess file. Make sure you have not specified unsupported directives inside the local .htaccess file. Such include PHP settings and Apache module settings.

    When I change the file permissions, I get a similar 403 error.

    I deleted the .htaccess (containing only one line:

    Code:
    php_value memory_limit 16M
    Now I get a blank screen. Looking at the page source reveals there is ... nothing. No error message, nothing.

    The administrators couldn't find anything, but gave me this message:

    I have again reviewed your case and I can confirm that the 500 Internal server error was caused by the directive in the file.

    Once I removed this line, the internal server error was resolved but your forum displayed a blank page. I have traced the execution of the index.php file of your forum and I noticed that the execution gets interrupted without error messages after certain template data is being read from the database.

    I believe that you need to consult the vBulletin support team regarding this problem.

    Below is the debug information I received when tracing your scripts, the part just before the execution was interrupted:

    Are you sure you actually copied over the complete database?

      Re-upload index.php whilst your FTP program is set to upload in ASCII format.

        If it had been that easy *sigh*. The ftp program loads up all those files as ASCII on default, but comparing file sizes something is wrong anyway 8(. Going through Lynne's link above.

        Thanks for your help!

        Hmm. There was some mix-up of 3.8.6 and 3.6.8 files. I am now uploading the files into a new directory and go from there.

        As it goes I did NOT upload the entire database: I skipped on the contents of the table 'attachments' since they make up about 90% of a 500 MB SQL dump. phpMyAdmin kind of balks at uploading the separated files (all under 50 MB, done with SQLDumpSplitter).

        Would that be a problem?

          Still the same error message in the forum root:

          500 - Internal Server Error

          This is a temporary server error.

          I do get a login at /admincp/ now, but when I enter my admin data it just reverts to login (after saying "thank you for logging in). If I enter a wrong username, it brings me to /login.php?do=login - that's the first page that looks like it's supposed to ;-).

          Through the drop down menu I was able to access pages displayed via /forumdisplay.php?f=... , but login still isn't possible.

          PHP version is 5.25. Actually phpinfo tells different from cPanel.
          PHP version is 5.2.17 CGI

          display_errors STDOUT STDOUT
          display_startup_errors Off Off
          hmm. disabling the php_value memory_limit 16M in .htaccess now actually let's me see the forum, but I still can't login...
