Re: [Fwd: [Phpwiki-talk] fresh installed 1.3.10 gives blank page]

Start dropping breadcrumbs (e.g., "print" statements, or printing to a 
file).

Start in index.php. At the end of it, it includes main.php. Thus, 
probably look into which functions are called from main.php, and drop 
breadcrumbs there too. Find a spot where the breadcrumbs are being 
printed, and another (later) spot where they aren't. Bring those two 
spots together until you see the exact line where execution ends. Print 
out some variables near that spot.

P.S. Here are a couple functions I dropped into my stdlib.php to help 
this process:

function simpleTrace($bt) {
    //print_r($bt);
    $s = '';
    foreach ($bt as $i => $elem) {
        if (!array_key_exists('file', $elem)) {
            continue;
        }
        $s .= "  " . $elem['file'] . ':' . $elem['line'] . ':' . 
$elem['function'] . "\n";
    }
    return $s;
}

function toDebugFile($s) {
    $fp = fopen("/tmp/phpwiki-dfrankow.txt", "a");
    fwrite($fp, $s . "\n");
    fclose($fp);
}

Then if I want a complete stack trace to a file, I do:

  toDebugFile(simpleTrace(debug_backtrace()))
