This plugin makes a copy of your web page on the server and by doing so it speeds up page load time and reduces the resource consumption. It is essential that you have this plugin just incase if your site hits the Front Page of a social media network such as digg or stumbleupon, without this plugin, your server will most likely crash.

In this tutorial, we will show you how to install WP Super Cache Plugin. Then we will walk you through the process of setting it up which will include updating the .htaccess files and selecting the right settings. Many beginners are afraid to install this plugin because it is a some what complicated setup.

excellent explanation for beginners
Nice article. My regular set-up used to revolve around Super Cache in addition to a DB cacher and php Speedy, before I switched to W3 Total cache.It combines and minifies js & css in addition to caching.
What about enabling compression?
That depends on whether your host supports it or not.
Gzip compression is an essential performance win any site. Enable it, your hosting provider plays no part in whether or not this works for you as far as WP Super Cache is concerned. If you want to compress other text based files, then you will need to do some quick checking to see what your options are. Or you can use W3 Total Cache, which will handle your posts/pages, feeds and CSS / JS if you minify them.
What are your thoughts on the W3 Super Cache plugin?
All reviews that we have heard of it says it is a great plugin.
Why that?
If you only want to compress, to save queries or to cache, you must not change anything on the server.
Sorry, but this is simply not true. W3 Total Cache supports all conceivable hosting paradigms, except some very advanced database implementations. In other words, from shared hosting to multiple dedicated servers. If you have a dedicated server, then you have a higher traffic site and thus installing software to get more performance is something one would desire.
Fredrick,
Thank you for the clarification. We have edited our comment, so it does not cause any confusion.
Would you recommend using this plug-in in conjunction with the DB Cache plug-in?
I have enabled them both together but I cannot see a performance increase.
Unless your site has high volume of DB queries, you should not need to run both. WP Super Cache can do the job for most sites.
Database caching reduces the “creation time” for new pages. In other words, a database cache allows you to build a new cache for your pages faster. So this handles cases like: user visiting a page that is not yet cached, generating the updated cached page for users that are not logged in etc. Reducing the load on your database server will also improve your WP Admin performance as well and give you more CPU power to focus on sending pages to visitors.
Hi — I followed the instructions but, at the top of the options page, I’m receiving a message that the file path is “writable.” I’m new to WP (as of this week) and would like to know what this means, any threat it may pose, and the way to fix it.
Thanks so much!
Hello Rachel,
For privacy reasons, lets talk about this over email. Please use our contact form and send us an email. This problem is solvable, and it needs to be solved asap.
If my hosting is with a company other than those you recommend what are the re-write rules I need to apply to the WP-Super Cache files/folders to ensure that it works?
Hey Clive,
You can find the .htaccess code here: in the installation page
Very useful description. A lot easier to understand than the one on the WordPress official plugin page.
Thanks, this article help me a lot.
But for step 4, is it obligation or just optional. How if my web host not support?
If your host does not support it then you can’t use this plugin.
how to make the folder readonly ! the public html file and it ask many save option and direct cached file, what can we do for that !!
Just what I needed.
I notice that you say “You will be able to update this only if your web host has correct folder/file permissions setup”
What permission should htaccess have for this to work?
The file needs to be writeable.
I have these 2 messages in the “fix configuration” section:
Bad Behaviour support is disabled.(Only half-on caching supported, disabled compression and requires Bad Behavior in “/home2/marjorj1/public_html/2010mysd/wp-content/plugins/bad-behavior/”)
No Adverts for Friends plugin is disabled. (requires friendsadverts.php too)
Do I need to enable both of these? Thanks!
WP Super Cache must not be set to Half-on Caching. And the Gzip compression must be disabled.
If you are not using Bad Behavior and it is just sitting there, then delete it. Same goes for Adverts plugin.
I have installed WP-Super-Cache
and receive this error message:
Error: Your cache directory (/home/mobixone/public_html/wp-content/cache/) or /home/mobixone/public_html/wp-content need to be writable for this plugin to work. Double-check it.
Cannot continue… fix previous problems and retry.
even i have make it writable.
Please reply fast if anyone know about it?
