How to fix this?

In short, there is no specific solution for this error. Check this answer to know more.

Yes if can be frustrating when you have an error and you say you did not change anything.
But you did change something and now there is an error
Change the Theme back to DefaultClean and see if you still have an error
If you have no error reinstall the original backup copy of the Theme you changed which was working
