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.

I just successfully changed the prefix of a WP 5.2.2 Multisite installation. Immediately after the plugin changed the prefix, the site was broken, but all I had to do was update $table_prefix in wp-config.php and then everything was fine. It also worked in regular WP 5.2.2 without the need to edit wp-config.php

I just tried this plugin and it worked perfectly. I saw that all of the 1-star reviews were from 2+ years ago. I was concerned. But, I'm suspecting that the plugin was corrected since it worked fine in my situation and, that there haven't been any other 1 star reviews for years. Note: As of 5/25/2019 I am running the most current version of this plugin as well as the most current version of WordPress. So from what I am seeing, it should be considered good and I wouldn't expect the problems that were reported 2+ years ago. Thumbs up to the developer of this plugin. Thanks, Gary Gordon

Plugin works for updating the prefix of the database tables, but you have to manually adjust your prefix in the wp-config.php file. I tested it with WP5.2 and the file permissions of wp-config.php temporarily set to "777". Despite of that, the wp-config-file did not get updated. Not big of a deal, after changing the prefix myself in the wp-config-file, everything worked just fine (i.e. my site was not "broken" anymore)
