Install Better Search Replace like you would install any other WordPress plugin.

Dashboard Method:

  1. Login to your WordPress admin and go to Plugins -> Add New
  2. Escribe «Better Search Replace» en la barra de búsqueda y selecciona este plugin
  3. Click «Install», and then «Activate Plugin»

Upload Method:

  1. Unzip the plugin and upload the «better-search-replace» folder to your ‘wp-content/plugins’ directory
  2. Activate the plugin through the Plugins menu in WordPress


Using Better Search Replace

Once activated, Better Search Replace will add a page under the «Tools» menu page in your WordPress admin.

Is my host supported?

Yes! This plugin should be compatible with any host.

Can I damage my site with this plugin?

Yes! Entering a wrong search or replace string could damage your database. Because of this, it is always adviseable to have a backup of your database before using this plugin.

How does this work on WordPress Multisite?

When running this plugin on a WordPress Multisite installation, it will only be loaded and visible for Network admins. Network admins can go to the dashboard of any subsite to run a search/replace on just the tables for that subsite, or go to the dashboard of the main/base site to run a search/replace on all tables.

How can I use this plugin when changing URLs?

If you’re moving your site from one server to another and changing the URL of your WordPress installation, the approach below allows you to do so easily without affecting the old site:

  1. Backup the database on your current site
  2. Instala la base de datos en tu nuevo host
  3. On the new host, define the new site URL in the wp-config.php file, as shown here
  4. Log in at your new admin URL and run Better Search Replace on the old site URL for the new site URL
  5. Delete the site_url constant you added to wp-config.php. You may also need to regenerate your .htaccess by going to Settings -> Permalinks and saving the settings.

I feel misled as the 'dry run' option is NOT part of the free plugin but rather a paid option. Imho 'dry run' is essential in any search and replace plugin so advertising this plugin as 'free' is a bit misleading. Technically this plugin is free but unusable (way to dangerous/powerful) as such.

I was going to try doing some search and replacements, and chose to do the 'dry run' first, but apparently you can't view the results from the dry run, without upgrading to the paid version. This effectively makes it less than useless. I'm not going to run a search/replace on a table unless I can preview what's going to be changed first.

This really make my life better. For real. Since I found this plugin al my migrations are FLAWLESS. So simple so good. Thanks a lot!!!

I really wish I had installed this plugin first instead of spending two hours trying to find the bad URLs in the database manually. I installed the plugin and ran a "Dry Run" (no changes) first to find the offending content. I run the search/replace again and it worked perfectly.
