template.php issues: “Warning: Attempt to read property “______” on null
Website: thejourneyschool.org
I keep getting error messages (not every time, but often) when I am customizing. All the errors are on template.php. The list of errors appear above the content of the website (on the website background.)
I'm using the most recent Clean Education Pro 3.4.1
These are the error messages (X=alpha numeric character):
