How to make Chrome, Opera and Safari working with codepress
#1
As you can see here (http://dev.mybb.com/projects/mybb/reposi...depress.js) there were some workarrounds because chrome, opera and safari don't work with codepress. Here is the solution:

1. Replace /admin/jscripts/codepress/codepress.html with:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html>
<head>
	<title>CodePress - Real Time Syntax Highlighting Editor written in JavaScript</title>
	<meta name="description" content="CodePress - source code editor window" />

	<script type="text/javascript">
	var language = 'generic';
	var engine = 'older';
	var ua = navigator.userAgent;
	var ts = (new Date).getTime(); // timestamp to avoid cache
	var lh = location.href;
	
	if(ua.match('MSIE')) engine = 'msie';
	else if(ua.match('AppleWebKit')) engine = 'webkit'; 
	else if(ua.match('Opera')) engine = 'opera'; 
	else if(ua.match('Gecko')) engine = 'gecko';

	if(lh.match('language=')) language = lh.replace(/.*language=(.*?)(&.*)?$/,'$1');

	document.write('<link type="text/css" href="codepress.css?ts='+ts+'" rel="stylesheet" />');
	document.write('<link type="text/css" href="languages/'+language+'.css?ts='+ts+'" rel="stylesheet" id="cp-lang-style" />');
	document.write('<scr'+'ipt type="text/javascript" src="engines/'+engine+'.js?ts='+ts+'"></scr'+'ipt>');
	document.write('<scr'+'ipt type="text/javascript" src="languages/'+language+'.js?ts='+ts+'"></scr'+'ipt>');
	</script>

</head>

<script type="text/javascript">
if(engine == "msie" || engine == "gecko" || engine == "webkit") document.write('<body><pre> </pre></body>');
else if(engine == "opera") document.write('<body></body>');
</script>

</html>

2. Make a new file /admin/jscripts/codepress/engines/webkit.js and fill in the following code:

3. Delete the mybb workaround in /admin/jscripts/codepress/codepress.js
This part here:
if(MyBB.browser == "opera" || MyBB.browser == "safari" || MyBB.browser == "chrome")
        {
                return;
        }

It works on mine. Have fun with it! http://dev.mybb.com/issues/1368
Best regards,
Michael Malin
