I got the following error in Opera:--

Notice: Undefined variable: gzdata in system/library/response.php on line 50

The relevant line of code reads --

Code: Select all: $gzdata .= gzencode($data, (int)$level);

Changing this to --

Code: Select all: $gzdata = gzencode($data, (int)$level);

resolves this error.

However, the biggest issue is character display. See attached screenshot.

Fido
In \catalog\view\template\module/layout.tpl

swap line 1 with line 3
I think that will cure the rendering problem.

I encounter the same problem. I manage to resolve the $gzdata error using Fido instructions.

I also changed the layout.tpl template. The correct code I presumed should look like this:

Code: Select all: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" dir="<?php echo $direction; ?>" lang="<?php echo $language; ?>" xml:lang="<?php echo $language; ?>"> <?php echo '<?xml version="1.0" encoding="UTF-8"?>' . "\n"; ?> <head>

But the strange characters are still there.

I can confirm this bug: I get the strange characters in Opera 9.63 and in Konqueror 4.1.3.

As a quick workaround, don't use the compression for the response output:

Code: Select all: private function compress($data, $level = 4) { // if (strpos(@$_SERVER['HTTP_ACCEPT_ENCODING'], 'gzip')) { // $encoding = 'gzip'; // } // if (strpos(@$_SERVER['HTTP_ACCEPT_ENCODING'], 'x-gzip')) { // $encoding = 'x-gzip'; // } ......

This is not a complete solution, but at least it gets Opera and Konqueror going again.

i'm posting a fix for this in the next release. I think the strange charater problem issomthing to do with the database installer.

Copy and paste this into your response class:

Code: Select all: <?php final class Response { private $headers = array(); private $output; public function addHeader($key, $value) { $this->headers[$key] = $value; } public function removeHeader($key) { if (isset($this->headers[$key])) { unset($this->headers[$key]); } } public function redirect($url) { header('Location: ' . $url); exit; } public function setOutput($output) { $this->output = $output; } private function compress($data, $level = 4) { if (strpos(@$_SERVER['HTTP_ACCEPT_ENCODING'], 'gzip')) { $encoding = 'gzip'; } if (strpos(@$_SERVER['HTTP_ACCEPT_ENCODING'], 'x-gzip')) { $encoding = 'x-gzip'; } if (!isset($encoding)) { return $data; } if (!extension_loaded('zlib') || ini_get('zlib.output_compression')) { return $data; } if (headers_sent()) { return $data; } if (connection_status()) { return $data; } $gzdata = gzencode($data, (int)$level); $this->addHeader('Content-Encoding', $encoding); return $gzdata; } public function output($level = 4) { if ($level) { $ouput = $this->compress($this->output, $level); } else { $ouput = $this->output; } foreach ($this->headers as $key => $value) { header($key. ': ' . $value); } echo $ouput; } } ?>
