rdebock on "[Plugin: Crayon Syntax Highlighter] Internal Server Error for bbPress posts"

Hi,

After upgrading Crayon to the latest version it became impossible to load any bbPress forum posts. The forum itself loaded, but any individual post reported a 500 "Internal server error".

In the error_log I found the following, which could possibly be related:

[Wed Apr 13 07:39:28.862495 2016] [proxy_fcgi:error] [pid X:tid Y] [client Z] malformed header from script 'index.php': Bad header:
[Wed Apr 13 07:39:28.862541 2016] [proxy_fcgi:error] [pid X:tid Y] [client Z] AH01070: Error parsing script headers

Thanks in advance.
