PHP Fatal error: Class 'RedirectController'

Hi all,

We updated our site from Drupal 7.5 to 7.53 today.

We are having issues with site performance and notice the following error in the error.log:

[30-Jan-2017 13:07:09 America/New_York] PHP Fatal error: Class ‘RedirectController’ not found in /home/ /public_html/includes/ on line 8041

Does anyone know how to fix this error?

Thank you,


Drupal version:
