# Error in wp-includes/vars.php

 * Hi,
    My installation is a little bit clunky and via my Debug Log (see below) 
   I am receiving errors in the wp-include/vars.php file. Lots of errors but only
   from this file. Although I have no idea what this error is my question is: If
   I replace all the WordPress core files can I remedy this or is is something else
   altogether?
 * Thank you in advance for any guidance.
 * Kind regards,
    George
 * This is a sample there are many more errors of the same type in the log.

 * No make sure no file is corrupted during installation, try MANUALLY re-installing
   WP.
