 * Optimize Database after Deleting Revisions, this plug no longer activates on 
   WordPress 5.3, and it’s labeled as “Warning: This plugin has not been tested 
   with your current version of WordPress.”
 * Update is needed?
    How to make it work again on WordPress?

 * Hey wppit,
 * It’s fully WP 5.3 compatible, so it should work.
    Did you try to fully re-install
   the plugin?

 * Yes, I’ve tried reinstalling it, but it doesn’t activate anymore. Before WordPress
   5.3, the plugin worked perfectly.

 * Hey wppit,
 * Strange…
    It runs fine on my own 10+ websites (with WP 5.3)
 * I also didn’t get any other reports about this issue.
 * Do you have another website (or development / test version of your site) where
   you can test the plugin on?
 * What you also can try is to (temporary) disable all plugins except for mine and
   then try to activate it again.
 * peace,

 * I’m thinking that it could be a problem with WordPress 5.3, I had other plugins
   disabled, and I tried to enable another, it did enabled, but clicking the disable
   button now will not deactivate the plugin.
    Thanks,

 * OK, it now appears that the problems is the W3 Total Cache plugin. I clear the
   cache, but the problem persisted, then I disabled the W3 Total Cache and plugins
   starts working.

 * Hi,
    I contacted W3 total cache, and they walked me through the process to reinstall
   the plugin. Apparently everything is working again.
 * Thank you for your help.
