Title: bugs questions Last modified: July 10, 2017 --- # bugs questions * Resolved [Peter K](https://wordpress.org/support/users/dragy/) * (@dragy) * [8 years, 11 months ago](https://wordpress.org/support/topic/bugs-questions/) * Hello, * 1. I see negative number here, is that correct or bug? I’m always using keep revisions set to 1, if that is related to this. * Total savings since the first run: -64 KB * 2. when I set keep revisions to 0, the pages are not working correctly after. When I open page, change it but not save it, page is not showing on frontend, I must go back and save it. Generally, when I set keep revisions to 1, there is only actual version of page keeped, I also don’t see “Revisions” on page’s page. * So my question is, if value “1” should be minimum availabel number for “revisions to keep”. also (‘0’ means: delete ALL revisions) should be changed to (‘1’ means: delete ALL revisions) * thx Viewing 5 replies - 1 through 5 (of 5 total) * Plugin Contributor [cageehv](https://wordpress.org/support/users/cageehv/) * (@cageehv) * [8 years, 11 months ago](https://wordpress.org/support/topic/bugs-questions/#post-9306560) * Hey Dragy, * 1. I bet you use InnoDB tables. Optimizing them doesn’t mean saving space perse. * 2. If you change a setting, of course you need to press the save buttton… Revision“ 1”: it keeps the orginal and the latest revision. The latest revision is often( almost) identical to the current original page. * I hope this answers your questions. * peace, Rolf * Thread Starter [Peter K](https://wordpress.org/support/users/dragy/) * (@dragy) * [8 years, 11 months ago](https://wordpress.org/support/topic/bugs-questions/#post-9308204) * Thank you for your time. * 1. Can you show 0 KB instead of -64 KB, just to not confuse users? Because it looks like a bug or as plugin is not working. Or maybe you can detect inno tables and show text that optimization is done automatically? * 2. here is what is confusing for average user * – I delete revisions to 0 – I go to page and change “a” to “aa” and save it, still I dont see “revisions” option – I go to page and change “aa” to “aaa”, then I see “revisions” option – when I click on Revisions, I see current page“ aaa” and I can go back only to page “aa”, I can not go back to page “a”. * I think “problem” is when page exist, it doesn’t mean that revision of that page exist – that is what non-programmer users don’t get. * Just writing my thoughts, maybe you can change it to be more friendly, like revisions 0 will do revisions 1, and -1 will be 0. * Plugin Contributor [cageehv](https://wordpress.org/support/users/cageehv/) * (@cageehv) * [8 years, 11 months ago](https://wordpress.org/support/topic/bugs-questions/#post-9308535) * Hey Dragy, * 1. I prefer to show the actual values and not manipulated ones… But I will make a note of it in the FAQ * 2. I am not going to change the possible values for the number of revisions: 80.000+ websites have set their preferred value. If I change it now, all these people will be totally confused. * peace, Rolf * Thread Starter [Peter K](https://wordpress.org/support/users/dragy/) * (@dragy) * [8 years, 11 months ago](https://wordpress.org/support/topic/bugs-questions/#post-9327437) * Hello Rolf * what about new text: * (‘0’ means: delete ALL revisions; ‘1’ means: keep actual posts / pages as revision) * thank you * Plugin Contributor [cageehv](https://wordpress.org/support/users/cageehv/) * (@cageehv) * [8 years, 11 months ago](https://wordpress.org/support/topic/bugs-questions/#post-9327447) * Hey Dragy, * That’s not correct… * There is always the current (original) page, plus 0 or more revisions of that page. The current (original) page is NOT a revision. * peace, Rolf Viewing 5 replies - 1 through 5 (of 5 total) The topic ‘bugs questions’ is closed to new replies. * ![](https://ps.w.org/rvg-optimize-database/assets/icon-256x256.png?rev=3350597) * [Optimize Database after Deleting Revisions](https://wordpress.org/plugins/rvg-optimize-database/) * [Frequently Asked Questions](https://wordpress.org/plugins/rvg-optimize-database/#faq) * [Support Threads](https://wordpress.org/support/plugin/rvg-optimize-database/) * [Active Topics](https://wordpress.org/support/plugin/rvg-optimize-database/active/) * [Unresolved Topics](https://wordpress.org/support/plugin/rvg-optimize-database/unresolved/) * [Reviews](https://wordpress.org/support/plugin/rvg-optimize-database/reviews/) * 5 replies * 2 participants * Last reply from: [cageehv](https://wordpress.org/support/users/cageehv/) * Last activity: [8 years, 11 months ago](https://wordpress.org/support/topic/bugs-questions/#post-9327447) * Status: resolved
