I'm new to WP and I'm trying to use the Arras theme. When I go to the theme options, I try clicking on "post types & tax" and I get an error message saying, "Cannot load arras-posttax."
When I try clicking on "custom background," I get a similar message saying, "Cannot load arras-custom-background."
I get similar messages with each theme I've tried using, such as Swift and Producer.
Does anyone have any idea why I cannot access these parts to chage the theme?
Any guidance wouldbe greatly appreciated!
