I tested this on two different sites, one almost clean, another one well up and running. The same result on both of them. Misconfigured references in the database and wordpress error messages. Its no longer possible to save data to the database. This obviously also includes trying to install or unistall plugins. The website is dead in the water.

Been troubleshooting this for a while now, reading other users experiences with this plugin. The takeaway is that this is a kind of "Install and see how it goes" kind of deals.

Sitting here waiting to load in my backup, but guess what :)
This plugin used over 100.000 database-updates to run once. My webhost has a limitation on 100.000 udates pr. hour, so no backup goes back in for the next hour.

If for some reason one of your hobbies are to run head first (as fast as you can) into a brick wall, and by that I mean try to install this plugin........Pretty Please, with sugar on top, take a fresh backup :)

I consider Optimize Database an essential plugin for every website.

TOP Plugin

By eerkan on April 17, 2021

very good plugin, set up and it works automatically and clean the site.

Works as Scheduled

By Chris (justkeepdistance) on February 21, 2021

I am happy with this plugin but am removing a star as I cant see a recommended amount of times a day I should run the plugin.

Good plugin but leads to ongoing time-out errors

By Plugins and Snippets (pluginsandsnippets) on November 22, 2020

In principle this would be an excellent plugin but it always leads in time-out errors. In our view, the problem lies with the execution of the optimization process itself. There is no safeguard against time-out errors. This should be fixed as there must be better ways to code this.

added a spam user in my database and changed my home url

By kyurmshah on October 29, 2020

This plugin was working fine untill suddenly it added 2 users ([email protected]) ac to my sql database and also changed my home url to some spammy url that kept on redirecting. the issue was resolved as soon as plugin was disabled
