White screen of death, site hangs after installing theme

[gaia9]

Hello,

I hope someone can help me here.

I have been getting the "white screen of death" for my entire site when installing Suffusion into my WP. The issue actually preceded the updates, which I hoped would resolve them. I hope I won't have to reinstall WP from scratch.

Below is the error log that tracks the problem; this error repeats indefinitely (I have obscured some of the path data per *****). The page hangs, saying "waiting for http://www.davidseacord.com

[Tue May 15 13:05:25 2012] [error] [client ********] PHP Warning: readdir() expects parameter 1 to be resource, boolean given in /var/home/************/davidseacord.com/www/wp-content/themes/suffusion/functions.php on line 1050, referer: http://www.davidseacord.com/wp-admin/up ... a6df221bdb

and later,

[Tue May 15 13:16:23 2012] [error] [client *********] PHP Warning: readdir() expects parameter 1 to be resource, boolean given in /var/home/***********/davidseacord.com/www/wp-content/themes/suffusion/functions.php on line 1050, referer: http://www.davidseacord.com/wp-admin/up ... a6df221bdb

This doesn't make any sense. Neither of the files mentioned have any of the references described.
wp-content/themes/suffusion/functions.php on line 1050,

while (false !== ($file = readdir($handle))) {
foreach($exts as $ext) { // for each extension check the extension
if (preg_match('/\.'.$ext.'$/i', $file, $test)) { // faster than ereg, case insensitive
$files[] = $file; // it's good
++$i;
}
}

And, in a search through wp-admin/update.php, I found no instance of the term a6df221bdb

I've been using Suffusion since '09, and it is working nicely on several other sites right now.

My current setup is:
Mac OS X 10.6.8
Firefox 12.0
WP 3.3.2 (all plugins disabled)
Suffusion 4.2.0

Thanks in advance,

Richard

See this thread: viewtopic.php?f=4&t=7960&p=32954#p32954. The line numbers might be different from the ones in this thread, but the concept is the same.

Hello Sayontan,

Thank you for such a prompt reply! Following your recommended thread, I first commented out the verbatim code snippet in suffusion-css-generator.php (which actually started at line 571), and that granted me access to the admin area, but the site itself was still WSOD.

Then moving on to functions.php, I could not find a verbatim code fragment. But I hunted for the snippet suffusion_get_rotating_image and found a single instance embedded in this fascinating chunk:

/**
* Based on the Image Rotator script by Matt Mullenweg > http://photomatt.net
* Inspired by Dan Benjamin > http://hiveware.com/imagerotator.php
* Latest version always at: http://photomatt.net/scripts/randomimage
*
* Make the folder the relative path to the images, like "../img" or "random/images/".
*
* Modifications by Sayontan Sinha, to dynamically pass the folder for images.
* This cannot exist as a standalone file, because it loads outside the context of WP, so variables such as folder names cannot be fetched by the file automatically.
*
* @param $folder
* @return string
*/
/*function suffusion_get_rotating_image($folder) {
// Space seperated list of extensions, you probably won't have to change this.
$exts = 'jpg jpeg png gif';

$files = array(); $i = -1; // Initialize some variables
// if ('' == $folder) $folder = './';
$content_folder = WP_CONTENT_DIR."/".$folder;

$handle = opendir($content_folder);
$exts = explode(' ', $exts);
while (false !== ($file = readdir($handle))) {
foreach($exts as $ext) { // for each extension check the extension
if (preg_match('/\.'.$ext.'$/i', $file, $test)) { // faster than ereg, case insensitive
$files[] = $file; // it's good
++$i;
}
}
}
closedir($handle); // We're not using it anymore
mt_srand((double)microtime()*1000000); // seed for PHP < 4.2
$rand = mt_rand(0, $i); // $i was incremented as we went along
return WP_CONTENT_URL."/".$folder."/".$files[$rand];
}
*/

I commented out the colored portion, and the site is now visible again.

I have a concern still, that some of my plugins may have trouble, as the site is meant to be a photo gallery. But I'll cross that bridge when I get to it.

Thank you so much for your intimate knowledge of the code!
