How to activate revisions for custom post types

Just in case, won’t hurt to check your site’s wp-config.php file to see if revisions are potentially disabled.

This tutorial shows how to disable them, thus what to check for in case they’re already disabled.

Hi Michael,

I checked my wp-config.php, but there is no function about turning on or off revisions.

What else could I check?

Just to be certain, you have some posts that have revisions available, correct?

Asking because according to https://wordpress.stackexchange.com/questions/139031/enable-revisions-for-custom-post-type#comment225014_139035 the UI for it won’t show until you have some to work with

Great! A couple of changes saved and revision box appears. Thanks for your help!

Welcome.
