I am checking my theme with theme check and it is raising following warning:
WARNING: Your theme appears to be in the wrong directory for the theme name. The directory name must match the slug of the theme. This theme's correct slug and text-domain is prisma. (If this is a child theme, you can ignore this error.)
Although page slug I have used is prisma and also tried to rename the WordPress installation directory to prisma but still the error is persisting. Can anybody guide me how to resolve the issue?
