Using newest version of WordPress, I can see in debug mode this warning: Deprecated: preg_replace(): The /e modifier is deprecated, use preg_replace_callback instead in /Applications/AMPPS/www/mysitetest/wp-content/plugins/wp-code-highlight/wp-code-highlight.php on line 68 Hope it could be useful https://wordpress.org/plugins/wp-code-highlight/ Hi, you could fix that warning editing wp-code-highlight.php files located in wp-content/plugins/wp-code-highlight/wp-code-highlight.php Comment line 67-68 and add this line: //return preg_replace("/<pre(.*?)>(.*?)<\/pre>/ise", // "'<pre class=\"wp-code-highlight prettyprint$line_numbers\">'.wch_stripslashes('$2').'</pre>'", $content); return preg_replace_callback("/<pre(.*?)>(.*?)<\/pre>/is",function($m) { return '<pre class=\"wp-code-highlight prettyprint$line_numbers\">'.wch_stripslashes('$m[2]').'</pre>'; },$content); Hi, Just updated my PHP version from 5.4 to 7 and I was getting that error too. Your solution, @simone-camporeale, didn’t completely worked for me. I was getting literally this in each pre: $m[2] So I have modified simone.camporeale solution, and got this one that is working for me: return preg_replace_callback("/<pre(.*?)>(.*?)<\/pre>/is",function($m) { return '<pre class="wp-code-highlight prettyprint'.$line_numbers.'">'.wch_stripslashes($m[2]).''; },$content); Note it’s almost the same, but modifying a little bit the pre tag’s class and removing the apostrophes in the wch_strpslashes() parameter. EDIT: sorry for editing a lot. First time posting here and I was trying to figure out how to correctly put code in the code blocks. EDIT2: btw, I had to check all my code snippets since, on some, some symbols like & or > were automatically changed to the HTML name (& amp; and & gt; respectively) Hi @pauguillamon , noticed that your snippet is missing the closing element in case others are using your patch. return preg_replace_callback("/<pre(.*?)>(.*?)<\/pre>/is",function($m) { return '<pre class="wp-code-highlight prettyprint'.$line_numbers.'">'.wch_stripslashes($m[2]).''; },$content); @michael Visser: Sorry, but you also forgot the closing pre tag. Here’s the code that works for me ATM. // return preg_replace("/<pre(.*?)>(.*?)<\/pre>/ise", // "'<pre class=\"wp-code-highlight prettyprint$line_numbers\">'.wch_stripslashes('$2').'</pre>'", $content); return preg_replace_callback("/<pre(.*?)>(.*?)<\/pre>/is",function($m) { return '<pre class="wp-code-highlight prettyprint'.$line_numbers.'">'.wch_stripslashes($m[2]).'</pre>'; },$content); *headsmack* Thanks @hoelli , we’ll get there on the third attempt (or more) 😉

Hi, you could fix that warning editing wp-code-highlight.php files located in wp-content/plugins/wp-code-highlight/wp-code-highlight.php Comment line 67-68 and add this line: //return preg_replace("/<pre(.*?)>(.*?)<\/pre>/ise", // "'<pre class=\"wp-code-highlight prettyprint$line_numbers\">'.wch_stripslashes('$2').'</pre>'", $content); return preg_replace_callback("/<pre(.*?)>(.*?)<\/pre>/is",function($m) { return '<pre class=\"wp-code-highlight prettyprint$line_numbers\">'.wch_stripslashes('$m[2]').'</pre>'; },$content);

Hi @pauguillamon , noticed that your snippet is missing the closing element in case others are using your patch. return preg_replace_callback("/<pre(.*?)>(.*?)<\/pre>/is",function($m) { return '<pre class="wp-code-highlight prettyprint'.$line_numbers.'">'.wch_stripslashes($m[2]).''; },$content);
