Change Table Prefix


Latest version compatible with WordPress multisite installation here

This plugin is mainly useful if you have not changed the database prefix at the time of installation and want to change post installation to make your website more secure and protected from SQL injections. With the use of this plug-in you can easily replace your database default prefix to any other prefix in single click.

As in most of the cases adminer are not changing the WordPress default database table prefix, it is easy for any hackers to inject to your database as all the default tables names are know for all. But if you modify your database tables prefix then your tables names are become unknown to outside world.

Plugin works great

I have the latest version of WP (4.8.1) – plugin changed prefixes without any problem, showing useful statistics how many tables were altered. I recommend this plugin over changing tables manually.

Flawless execution

While setting up a bunch of sites I accidentally forgot to enter a custom prefix on one… this plugin took care of that (and gave me one less vulnerability on my Total Security report).
