I installed this plugin to solve the bloated database issue (100Mb size on a site with a few pages). It does what it says on the box and does it without errors.
I also love it that it is integrated with Updraft backups so I can take a database backup before optimising the tables. But again, never had any issues with it, it just magically reduces the db size with a single click. You can’t wish for more. 😉 Thanks for the great work!
