This is probably a simple problem, but this is my first attempt at using wordpress.
I've installed WP Super Cache, and have been following this guide
http://www.wpbeginner.com/beginners-guide/how-to-install-and-setup-wp-super-cache-for-beginners/
and then it links to this guide
http://www.wpbeginner.com/wp-tutorials/seo-friendly-url-structure-for-wordpress/
I update my permalinks to
Custom /%category%/%postname%/
The guide says that "Your .htaccess file will automatically be updated, and your URL will be changed. "
Except when I click save changes I receive the message
"You should update your .htaccess now."
With this written at the bottom
"If your .htaccess file were writable, we could do this automatically, but it isn’t so these are the mod_rewrite rules you should have in your .htaccess file. Click in the field and press CTRL + a to select all."
And some code under it
I am hosting with host gator. I have no idea where to find my .htaccess file?
Also, the guide says
"ou need to scroll down on the WP Super Cache option page screen until you see the Mod Rewrite Rules Section."
I cannot find this section anywhere!
Any help is EXTREMELY appreciated. Thank you
