SyntaxHighlighter Evolved

Just what I was looking for.
Thank you guys.

Perfect

I'm a longtime user of syntaxhighlighter evolved, so thanks for the excellent plugin!

The only downside I've recently experienced is the lack of bbPress integration, hence 4 stars rather than 5. If you need this for non-bbPress projects, this is a great choice.

longtime fan, but no bbpress support


It works and show code beautifully on pages, But if you copied that code and want to use it, the it shows errors, Looks like it add some spaces,



I tried it with php shorcode, and when i copied the code from the frontend of the page, It gives Parse error: syntax error, unexpected...


Works, But if you copy code and wan to to use it show error
