syntax highlighting

[snippsat]

Im wondering if we might be running an older version that does not have these issues fixed.

maybe if we compare and contrast the plugin code between the latest github code, these issues might of been resolved.

Yes running an older version,the problem is that there no info about SyntaxHighlighter v4 and MyBB.
V4 use different tool to build npm.
You can ask MyBB staff about this.

based on this issue
https://github.com/syntaxhighlighter/syn...issues/366

it looks like the devs expect you to escape the HTML

Yes,but now i was trying to fix error @ichabod801 post about.
[shcode=python]print('Hello world')[/shcode]

I will try later to run XRegExp.js together with the fix i have applid to uncompressed shCore.js.
