  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.

Its a bait & switch. They say nothing in their «free» version description about there even being a paid version. All the free version will tell you is how many replacements will happen. But it won’t show you what they are. So its not safe to use, and their description is misleading.

I just used this tool. At first it failed to replace links within my WordPress Elementor templates, within pages, and in the global footer for my site. Also, the URLs of the templates were still tied to the old website address and were still giving me a «file not found»when I clicked on them in my Elementor template list to try to edit them. I downloaded my templates and looked at the content of the JSON file of a template with a text editor. I found that its URLs were stated this way:\/directoryname (with a back slash and forward slash instead of just a forward slash). So I re-ran this plugin to search for that string and replace it with That worked for changing the links in pages and the global footer. However, the problem with opening a template changed from file not found to it now won’t load. Working on that.

This plugin gets the job done as described. The progress indicator bar is a good feature. Search result details are only available in paid version.
