 * Hi there, we have multiple sites running the security plus firewall. I have seen
   a few email reports of malicious code and md5 hashes on /wp-includes/Text/Diff.
   php but have confirmed the file to be the match of the core file in their git
   repo. [https://github.com/WordPress/WordPress/blob/master/wp-includes/Text/Diff.php](https://github.com/WordPress/WordPress/blob/master/wp-includes/Text/Diff.php)
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Ffalse-positives-on-wp-core-wp-includes-text-diff-php%2F%3Foutput_format%3Dmd&locale=en_US)

 * Thanks for reply.
 * In my screen, there’s no “Send for analysis” maybe “denied”.
   How can I send analysis?
