    That's right. and I know it's something completely stupid on my part, but I just can't seem to find the problem.
    I unpacked Vanilla 0.9.2.6 in a folder, and got a name-based virtual host pointing to it. Now that's working. any test PHP file in there gets parsed correctly.

    I used the manual install procedure for vanilla.
    As far as I can tell, I did everything correct.
    And the big problem is....I don't have an error. the page just returns:

    <html><body></body></html>. that's it.
    and that's probably default in firefox.
    So my guess is that it's returning nothing actually....

    It seems like al the "include" stuff in the index.php just doesn't "include" anything, but isn't resulting in an error either.
    When I intentionally screw up the path in appg/settings.php, I *DO* get an error about files nog being found. So, it seems that the path is not the problem. something with rights then? (altough i'am pretty sure all the files have read permissions at least)

    Does anyone has a clue?
    Please tell if I have to post any configuration.

    any help is greatly appreciated.

    PHP version: 4.4.0-6

    Well, that's really odd.

    If I were in your shoes, I'd take the route of echoing test strings in the files until I found where the parsing failed. Start at the top of the index file and make your way through the includes.

    The automatic installation failed with the same problem on page 3.
    "Click here to create Vanilla's database tables and proceed to the next step"
    I get an empty page with no error.

    I tested if I could use PHP to write to a file (using fwrite) with the same rights as the files used by vanilla, and it worked.
    I also test to see if a simple echo worked in index.php.
    That worked, and it triggered an error:

    This is a test <-- // This is the echo();
    Warning: Cannot modify header information - headers already sent by (output started at /srv/www/vhosts/test.sermo.nl/index.php:13) in /srv/www/vhosts/test.sermo.nl/appg/headers.php on line 14

    I also put an echo test in "appg/init_internal.php"
    and it worked. So includes work...but some of them not?
    phew. that's weird. and I'am not so sure includes are the problem anymore....

    If I remove the echo's, I end up with no output at all again.
    Maybe it is something with mysql ? (Does index.php make a connection?)

    I'm thinking it's most likely mysql that is giving you the headaches.

    In 0.9.2.6, the database connection is made in library/Utility.Database.class.php on lines 103-105:

    $this->Connection = @mysql_connect($Host, $User, $Password);
    if (!$this->Connection) $Context->ErrorManager->AddError($Context, $this->Name, "OpenConnection", "The connection to the database failed.");
    if (!mysql_select_db(dbNAME, $this->Connection)) $Context->ErrorManager->AddError($Context, $this->Name, "OpenConnection", "Failed to connect to the '".$Name."' database.");


    The first thing I'd try is echoing something before line 103 to make sure that the parser is getting that far.
    Then I'd also try echoing something after line 105 to make sure it's not getting through this code.

    Then I'd remove any @ symbols from those lines so that any error messages are spit out to the screen. The Vanilla code is meant to capture those errors, but from time to time in various setups it fails to do so.

    Allright. Both echo before 103 and after 105 are printed.
    When removing the @ symbol in "@mysql_connect" etc..

    I use SuSE 10.

    Ok it was the mysql module! thanx Mark, ithcy and Bergamot!
    I thought Yast auto-installed it, but it wasn't installed.
    But, vanilla doesn't give any error in that direction unless you get rid of the "@" as described by Mark in above post.

    I really thought I was there, but noooooo. on to the next error:

    Fatal error: Call to undefined function: session_id() in /srv/www/vhosts/test.sermo.nl/library/Vanilla.Session.class.php on line 63

    http://nl3.php.net/session:

    However, maybe not in SUSE:

    I had a feeling you were going to run into that problem. Don't know why.

    There have been a slew of people running into that one lately.
    The first thing to make sure is that the controls/index.php file is actually there.

    There is a pretty good discussion about this error here:

    The workaround
    if ($this->SelfUrl == "haliki") $this->SelfUrl = "index.php";
    didn't work. :(

    removing the @ yields:

    I'm assuming you replaced 'haliki' with the name of your folder?
    It looks there though asif your paths are wrong in your appg/settings file. Care to paste the relative sections?

    "$PHP_SELF
    $PHP_SELF is deprecated and should not be used because it will not work without register_globals being enabled. As of PHP 4.2.0 the default for the PHP directive register_globals
    went from on to off."

    Could it be, that since my "register_globals" are off by default, this is causing a problem?

    Hmmm. I tried to look at your http://test.sermo.nl/ url, but it failed to load at all.

    Assuming that the controls/index.php file is there, I'm not really sure what to tell you.

    I guess the next thing I'd try is creating a test page with an include to that file.

    So, in the vanilla root, create test.php with this in it:

    <?php
    include('controls/index.php');
    echo('Did that work?');
    ?>

    If *that* fails, then the file definitely isn't there or there is something wacky going on in your php config.

    No, that actually included properly. There is a class within controls/index.php that is derived from another class not in that file, so it threw the error.

    Let's try something different. Let's try changing the file's include path to be explicit directly from root.

    In your appg/init_internal.php file, change line 92 from this:

    $Page->Import($Context->ControlFile);

    To this:

    $Page->Import('/srv/www/vhosts/test.sermo.nl/'.$Context->ControlFile);

    If that doesn't work, then let's try changing line 92 to this:

    include('/srv/www/vhosts/test.sermo.nl/'.$Context->ControlFile);

    If either of those work, you'll need to do the same thing in appg/init_external.php.

    Yeah, it did work, then.

    The reason you got another error is because the index page loaded properly, and then found that you weren't signed in, so it redirected you to the sign in page.

    The Sign in page uses a different init_ file (init_external.php), so you will need to make that change to the init_external.php file as well.

    Get that sorted, and then we'll move on to the next issue.
