Error message

[Topic changed to more accurate one – it has nothing to do with the Codex]

Hey Guys,

I am getting an error when I try to edit de html of my site it says:

Warning: scandir(/home/content/39/10542739/html/wp-content/themes/graphene) [function.scandir]: failed to open dir: Permission denied in /home/content/39/10542739/html/wp-includes/class-wp-theme.php on line 980

Warning: scandir() [function.scandir]: (errno 13): Permission denied in /home/content/39/10542739/html/wp-includes/class-wp-theme.php on line 980

I tried contacting my theme support (graphene) and they said:
“The issue you’re describing is a permission issue on the server, not caused by the theme. FTP to your site and change the files and folder permissions to the appropriate ones. If you don’t know how to do that, contact your hosting provider and ask them to do it for you.”

And then I tried contacting the hosting and he said it had nothing to do with the hosting (godaddy) because the site is up fine. he said I should contact wordpress because it is something with the codex.
