Have the same issue here with this fatal error message:
l error: Call to undefined function is_rtl() in /home/ssrad/courses.sexyspirits.com/wp-includes/general-template.php on line 2102

seems best to not even mess with this upgrade if I have to do other actions to fix the bugs. your suggestion?

Same problem here.
I now cannot log in to admin area and I get this message:
l error: Call to undefined function is_rtl() in /home/ssrad/courses.sexyspirits.com/wp-includes/general-template.php on line 2102

SwakyKant, what exactly was your temporary solution and what did you do??
