  • Fatal error: Call to undefined function: is_browser()

    Hi...

    i just tried to upgrade from vb3.04 to 3.07,
    i uploaded the new files and then when i tried to
    run the /install/upgrade.php script , i got this error:
    Fatal error: Call to undefined function: is_browser()
    in global.php line xxxx

    in the line "xxxx" there's a call to the function is_browser()
    that resides in the file /includes/functions.php
    and do EXISTS in the new (already uploaded) functions.php file
    but it's not found by global.php ...

    In the file global.php, the functions are loaded this way:
    require_once('./includes/functions.php');
    so i guess the OLD functions.php file was loaded ONCE
    and then stored in some place to avoid reloading the file...
    the problem is that global.php does not load the new file now...

    Whan can i do?

    i already tried to empty the browser temp files,
    cache, reload the page, etc
    but the error is still there...

    Any suggestion?

    Sounds like you don't have all of the files uploaded properly

      the files are uploaded correctly, (double-checked permissions and ascci transfers)

      i'm pretty sure that the problem resides on the script instruction:
      require_once('./includes/functions.php');
      that still has the old file loaded in somewhere
      and is not loading the new one, because it already
      loaded it once..


      any ideas?

        Honestly, it's hard to see how you could get this error with the original vB files in place. Specificcally this function is defined in includes/functions.php.

          the functions.php file was modified to work with some hack-addon,
          but i'm 100% sure that is not the hack/modification itself...

          I just did this bug-test, please read:

          i uploaded the original vb file: /includes/functions.php
          and there were not problems ...

          then i opened the original file in my HHDD,
          and i modified it in just one line of code (added a small comment) :

          // this is a small comment

          i saved the file and uploaded again
          and i got this error:
          Parse error: parse error in /var/www/html/forum/includes/functions.php on line 2019

          Fatal error: Call to undefined function: is_browser() in /var/www/html/forum/global.php on line 59
          what's wrong?.....

          how can i manage to reinstall all my modifications

          any sugestion?
