Thanks so much for your reply. I deleted the classic and default theme and now my page shows up blank. I tried uploading a theme and got the above error message.
I am thinking of uninstalling WordPress altogether. I’ve tried everything to reinstall from reading other posts. I’ve tried downloading WordPress Install again and just uploading the default and classic themes but it still doesn’t show on my site. It still shows the same error message.
I’ve posted at Blue Host in case it’s something that needs to be fixed on their side. I also changed the permission for the default from 644 to 755 because I recall that was the permission before.
Thanks for any help.
