Entire Website Displayed in Plain HTML Version

Did you change themes and then not reset your menu to primary?

Thank you for replying and no I’ve had this theme the entire time I’ve been creating the website.

This appears to be Menu based from what I see. Go to your menu screen, make sure Primary is checked and save it again.
OK, I just checked and your Home page looks great..

Thank you so much for your help. I did what you said and decided to go with a new theme.

So glad to hear you got it working..
