TWEAK: Update class-udrpc to latest (1.4.14) which removes a conflict with other code that may interact with CORS OPTIONS requests
TWEAK: Escape log lines when sending for display (theoretically an XSS security issue, but to achieve a successful attack, someone would have to first get something malicious into the log file, which is difficult as there are not many places where foreign input can end up in the log file - e.g. hack into Dropbox and cause Dropbox to send you back malicious HTML in an error message - and then be able to persuade you to both take a backup triggering the problem and then view the log file in your WP dashboard)
TWEAK: Marked as tested and compatible on WordPress 4.8
