I installed the most recent version of X.
Old pages that were made with cornerstone (such as my homepage) are not able to be edited in cornerstone.
My headers and footers are a mess.
This is what my site looked like before the update: https://web.archive.org/web/20170618160521/http://studentloansherpa.com/
This is what it looks like now: studentloansherpa.com
Is there a way to revert to a prior version of x?
