Help with error message

  • I just upgraded and now I have a white screen with this error message:

    Fatal error: Call to undefined function is_rtl() in /home/content/d/a/r/darenvarner/html/wp-includes/general-template.php on line 2102

    Please help. I don’t know much about how to fix this. And please keep it simple as I am a novice.
