WordPress is controlled by its database. You can’t display a post properly if your database is corrupted as sometimes the categories and tags are wrong or sometimes you can’t even login.
However, corrupt WordPress databases happen more than you would have liked. And it could be due to a variety of reasons, such as a faulty plugin installation, your WordPress being hacked, a server crash, a hardware failure on your server or a bug in MySQL, or seemingly for no particular reason.
However, before you panic, take a deep breath and know that there are simple ways to repair a damaged database.

Two things you should always do regarding WordPress databases: backup and optimization.
Optimizing your database is a lot like defragmenting your hard drive. It’s a way to clean up your database so it runs smoothly. Optimization helps clean up your database and frees up disk space on the server.
Check out the following plugins to help you optimize your database:
• WP-Optimize – This plugin allows you to optimize and clean your database and perform other tasks easily and in just a few clicks.
• Clean Options – If you have orphaned options in your database, this plugin could help you clean them easily.
• WP Database Optimize: This allows you to set up a schedule for your optimization.
Backing up your database should help you recover if further database problems arise and these suggestions don’t work. Instead of losing your blogs, articles, and readers, you can simply restore a previous backup of your WP installation.
And this is how you fix a corrupt WordPress database.
