How to Disable or Limit WordPress Post Revisions Tutorial

It’s a popular WordPress myth that storing multiple post revisions slows down your website. This is not true. WordPress is written smart enough to ignore revisions while rendering the front end and its MySQL queries are written well enough so revisions don’t actually slow them down. However, post revisions take space in your WordPress database. Revisions are practically full copies of your posts, so if you have hundreds of posts this means you have few hundreds of revisions stored too.

If you need to decrease the size of your WordPress database, removing your post revisions is a great way to do it without sacrificing any actual content. To do this open the WordPress wp-config.php file and add the following configuration line to it above the “/* That’s all, stop editing! Happy blogging. */” line:

define('WP_POST_REVISIONS', false );

Doing this, however, will only tell your WordPress application to stop storing new post revisions. If you want to delete all the existing ones, it’s a good idea to use the Bulk Delete free plugin or a different one with similar functionalities.

If you do not want to disable the WordPress revisions functionality entirely, you can set a limit on how many revisions should be saved. This is done by adding the following line in the wp-config.php file above the “/* That’s all, stop editing! Happy blogging. */” line:

define('WP_POST_REVISIONS', 3 );

In the above, you can substitute 3 with the limit of revisions you want to have for each post.
