Here are the support infos for Hostgator.
How to login into cPanel (control panel):

How to use the file manager:

Now you need to reach your website’s WordPress folder, open it, and edit the file named: wp-config.php
Look for a line of code like this at the beginning (around line 15 to 20):
define(‘WPCACHEHOME’, ‘/YOUR ABSOLUTE PATH/wp-content/plugins/wp-super-cache/’ ); //Added by WP-Cache Manager
If it is not there, add it and replace the part “YOUR ABSOLUTE PATH” with your own path (given in the WordPress warning message).
If that line of code is already there, just compare the “path” with the one given in the WordPress warning message, make sure it is the same.
Hope this will help.
Like Steve ZeeZee, I was reluctant to ask BlueHost for help with this. I had to call twice … the first tech support simply told me to look it up on the ww.wp.xz.cn site. However, when I called back, I got a very patient and helpful person. He logged into the site and was able to get it working for me. Unfortunately, I don’t know exactly what he did. BlueHost tech support is wonderful!
