Hi NerdPress,
I’m happy to see your adoption of this useful plugin.
In checking the issues, I can report several things that happened both before and since version 5.2 was issued.
My settings have all boxes checked except Delete revisions older than. Number of revisions: 6 . No database table boxes are checked.
I had noticed while using the previous recent plugin versions that some old stable sites with no recent changes, or revisions the number of revisions saved had been reduced to 5!! In one case no revisions were reported or visible in the Classical Editor on some pages. This continued despite adding define( ‘WP_POST_REVISIONS’, true ); to the wp-config.php file, deactivating plugins and reinstalling WordPress. It seems that the revisions were deleted, but can now be added by repeatedly saving after small changes made to check the issue – this on a page which had been unchanged for 10 years!
Those problems aside, the issue I reported was after using the Optimize DB (one-click) on the Admin bar, it did not find any revisions and still does not show or fix them. However, after running the Analyze page it does report the revisions on the pages and other items and running Optimize does work.
