Comment 2 Oscar van Vliet 2004-10-08 15:28:58 UTC
Setting severity to major because the web-based installer won't work in this way
and the potential workaround requires some work. 
Comment 3 Brion Vibber 2004-10-08 18:19:31 UTC
Can those of you experiencing this problem provide a dump of output from the phpinfo() function? There 
must be something causing it...
Comment 4 Oscar van Vliet 2004-10-10 22:27:38 UTC
Created attachment 81 [details]
PHPinfo() output

This is my PHPinfo() output file. I took out the document paths and the IP
adress of the server over privacy considerations. Other info:

Apple iBook G4, 800 MHZ, 640 MB RAM.
Comment 5 Oscar van Vliet 2004-10-25 16:04:44 UTC
It seems like I found the bug that was bothering my installation, though I don't
understand why the implementation is wrong. The problem goes away when I comment
out the following lines in config/index.php

require_once( "../includes/MagicWord.php" );
require_once( "../includes/Namespace.php" );

It takes a while to complete, but now I managed to get a completed
localsettings.php.
Comment 6 Brion Vibber 2004-12-05 21:02:51 UTC
Please test with 1.4beta.
Comment 7 Oscar van Vliet 2004-12-08 22:21:59 UTC
I tested this with 1.4beta1 and the installation works smoothly.
Still there in 1.3.8, though..

Any projection as to when 1.4 is going to hit production stability?
Comment 8 Brion Vibber 2004-12-09 00:18:08 UTC
Thanks for the feedback! Resolving as fixed.

1.4.0 should be released within the next week or two.
Comment 9 Zigger 2005-01-05 13:53:09 UTC
*** Bug 1258 has been marked as a duplicate of this bug. ***
Comment 10 Oscar van Vliet 2005-03-21 15:01:09 UTC
Just installed 1.4.0 and got the old problem again.
I could still fix it in the same way: just comment out the two offending lines:

    # require_once( "../includes/MagicWord.php" ); 
    # require_once( "../includes/Namespace.php" );

Sorry. Though I am a lot more worried about bug 1727, which makes my wiki all
but unusable.
Comment 11 Brion Vibber 2005-04-22 12:03:53 UTC
Please test with 1.4.2; changes to the include path in the installer have been made.
Comment 12 Brion Vibber 2005-06-02 05:11:27 UTC
No response from user who reopened the bug. Resolving as FIXED again.
