WordPress Importer


The WordPress Importer will import the following content from a WordPress export file:

  • Posts, pages and other custom post types
  • Comments
  • Custom fields and post meta
  • Categories, tags and terms from custom taxonomies
  • Authors

For further information and instructions please see the Codex page on Importing Content


The quickest method for installing the importer is:

  1. Visit Tools -> Import in the WordPress dashboard
  2. Click on the WordPress link in the list of importers
  3. Click « Install Now »
  4. Finally click « Activate Plugin & Run Importer »

If you would prefer to do things manually then follow these instructions:

  1. Upload the wordpress-importer folder to the /wp-content/plugins/ directory
  2. Activate the plugin through the ‘Plugins’ menu in WordPress
  3. Go to the Tools -> Import screen, click on WordPress


Help! I’m getting out of memory errors or a blank screen.

If your exported file is very large, the import script may run into your host’s configured memory limit for PHP.

A message like « Fatal error: Allowed memory size of 8388608 bytes exhausted » indicates that the script can’t successfully import your XML file under the current PHP memory limit. If you have access to the php.ini file, you can manually increase the limit; if you do not (your WordPress installation is hosted on a shared server, for instance), you might have to break your exported XML file into several smaller pieces and run the import script one at a time.

For those with shared hosting, the best alternative may be to consult hosting support to determine the safest approach for running the import. A host may be willing to temporarily lift the memory limit and/or run the process directly from their end.

WordPress Codex: Importing Content


Fails most of the time

This is a very important plugin for migrating and merging WordPress content between sites and I used to use it a lot with much success. But now it almost always fails, getting stuck somewhere along the way or failing to import images. It’s disappointing that this plugin’s functionality is not officially supported by WordPress/Automattic.

Media gallery import broken

When trying to import a WordPress export file that includes Media, you get the following error:

Notice: wp_get_http is deprecated since version 4.4.0! Use WP_Http instead.

Is this plugin broken since versions 4.4.0 of WP core or higher?!?

Unbelievably bad and broken

I’m using this just to try to import the official theme unit test, and it turns out that this plugin seems developed in 1964.

I’m replacing real path with MYPRAVETEURL:


Notice: wp_get_http is deprecated since version 4.4.0! Use WP_Http instead. in /MYPRIVATEURL/wp-includes/functions.php on line 3831

[Moderated to delete giant paste. Please use pastebin.com or gist.github.com for large pastes.]

Rarely works well, but forced to use to migrate from wordpress.com

Obviously Automattic want to keep people on wordpress.com, yet still be able to claim an ‘open’ platform (but where’s the full source code, not just Calypso?), so they provide a sh1t plugin for migration to self-hosted wordpress.org.

It rarely works, let alone well, but seems to be the only tool available. Never use this plugin except to migrate from wordpress.com to self-hosted wordpress.org. Any other tool will always be better for any other job.

wordpress.org is open. wordpress.com is not. Do not use wordpress.com in the first place if you want to save yourself hassle in the long run. (I make money out of people who do, but I shouldn’t have to.)
