I disabled the posts revision feature according to this codex by placing this code in the wp-config.php:

define('WP_POST_REVISIONS', false );

But revions are still being saved by the WP. Why?

I am using wp3.1.3 and Twenty Ten theme. I have couple of plugins, and disabling them does not resolve the issue.

so when you add this code does it still show the post revisions in the edit post single page view? If so this is because there are already revisions present. This will only activate on new posts. You can always go into your db and manually delete the revisions – xLRDxREVENGEx Jun 4 '11 at 6:55
no this goes into your wp-config.php file – xLRDxREVENGEx Jun 4 '11 at 21:12
In the root of your wordpress directory is the wp-config.php file this is where it goes not your functions.php and your post above says wp-config.php – xLRDxREVENGEx Jun 4 '11 at 21:14
Sounds good. since i did not really answer the question can you give me an up vote on the solution at lease. – xLRDxREVENGEx Jun 5 '11 at 4:32
@xLRDxREVENGEx, I be glad to, but I don't know how to go about doing it. I don't quite understand many features of this website yet. – Tara Jun 5 '11 at 18:06

wp-config.php is suggested place for such definitions, because at any point later they might get replaced by default values during loading.

See Editing wp-config.php in Codex for thorough instructions.

Also worth noting that it's commonly said like add to the end, but really definitions should go above this line:

/* That's all, stop editing! Happy blogging. */

Or, if it was removed for some reason, above:

require_once(ABSPATH . 'wp-settings.php');

Try using this instead define('WP_POST_REVISIONS', 0);
I am currently using this on my wp-config.php file and it is working on my blog. (:
