Wish I could say that worked, but it didn’t. All folders are 755, but the custom folder still doesn’t come up in Appearance. I even have the custom folder in bbpress template and my templates and it’s not showing up.
I’m having the same problem. I changed the theme permissions to 0644, but the theme still doesn’t show in Appearance. 0644, by the way, is different than the kakumei permission. That theme is working.
