CSS editor not working

my site: www.thejollyrogerbus.com

When I try to make changes in style.css it sends me to the 404 page. What do I do? All of the other style sheets do the same thing.

Hello there,

Thank you for reporting.

I guess there is permission issue. Try to change the wp-content, wp-content/themes, and wp-content/sydney-pro-ii directories into 0755; the files which reside inside wp-content/sydney-pro-ii should be 644 or 640. You can change it from cPanel or FTP. Head on here for more details.

If it didn’t help, I’d strongly recommend you to consult to your hosting support as it doesn’t relate to theme’s issue.

Warmest regards,
Khars
