Recently I noticed that the character & is displayed in the SyntaxHighlighter like this: &
To fix this, simply add this snippet of the user kaggdesign to /var/www/html/wp-content/plugins/syntaxhighlighter/syntaxhighlighter.php
/** * Filter to fix issue with & in SyntaxHighlighter Evolved plugin. * * @param string $code Code to format. * @param array $atts Attributes. * @param string $tag Tag. * * @return string */ function kagg_syntaxhighlighter_precode( $code, $atts, $tag ) { if ( 'code' === $tag ) { $code = wp_specialchars_decode( $code ); } return $code; } add_filter( 'syntaxhighlighter_precode', 'kagg_syntaxhighlighter_precode', 10, 3 );
This can be done directly from the webinterface. Just go to Plugins -> Plugin Editor -> select the Plugin SyntaxHighlighter Evolved -> add the snippet to the end
