The color and font options do not work

When you change the color or font options in Theme Options, it does not work. The problem may be:

- It is cached by the following caches: hosting cache, caching plugin, browser cache and CDN. So please clear all caches after changing.

- The custom css file (the theme_name.css file in the uploads folder) was not updated. Please try changing the permission of the uploads folder to 777 and save Theme Options again.

- You don't have permission to create file on your wordpress directory. You need to change ownership. This article will help you http://www.chrisabernethy.com/why-wordpress-asks-connection-info/
