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:

- 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.

- Your site is cached by plugin, server or browser. You need to clear cache from browser and the caching plugin if you have already installed. If it still is not fixed, you should contact your hosting provider about caching.

- 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/
