Upgrading CiviCRM for WordPress¶
Use this document to upgrade CiviCRM installations on WordPress to the latest CiviCRM release.
Make sure you have done the steps listed in "Before upgrading" first.
Download the latest code¶
- Go to civicrm.org/download
Select the latest currently available CiviCRM tarball for WordPress.
Save this file in
If using localization, also download the latest version of the localization files. See the CiviCRM Localisation page about how to install files for running CiviCRM in languages other than American English.
Make sure you have logged in to WordPress as an administrator. Do not log out until the entire process is complete.
Upgrade the filesystem¶
Backup your settings files¶
The "Before upgrading" steps describe steps for backing everything up in case something goes wrong during the upgrade. In addition to this important safeguard, we also need to actually use the
civicrm.settings.php settings file, as it is, during the upgrade.
For Versions installed prior to 4.7
For Versions installed 4.7+
The installer in 4.7 does not assume that the content-dir is wp-content. It probably is, but can be renamed/moved as detailed here
Copy this file to a location outside your WordPress project. You will need to restore it after upgrading.
- Also, if you are using the
<wordpress_root>/wp-content/plugins/civicrm/civicrm/settings_location.phpfile in your implementation, make a copy of this as well.
Remove old CiviCRM code¶
CiviCRM will not run properly if files from previous version are present after the upgrade.
Make sure you have a good backup of your complete previous version installation
Unpack the latest package and relocate settings file/s¶
Unpack the files.
$ cd <wordpress_root>/<content-dir>/plugins $ unzip <civicrm_download_file>.zip
For Versions installed prior to 4.7 - Relocate (paste) the backed-up
If you have upgraded from a CiviCRM 4.1 version, check the contents of
civicrm.settings.php. Make sure at the very end of the file these 2 lines exist, and if not, add them.
require_once 'CRM/Core/ClassLoader.php'; CRM_Core_ClassLoader::singleton()->register();
If you are using the
<wordpress_root>/<content-dir>/plugins/civicrm/civicrm/settings_location.phpfile in your implementation, relocate this file from your back-up.
Install localization files (optional)¶
If your site requires the localization files, download the
civicrm-x.x.x-l10n.tar.gz from civicrm.org/download
These files must be untarred under
<wordpress_root>/wp-content/plugins/civicrm/. Please note the
tar.gz file only contains
$ cd <wordpress_root>/<content-dir>/plugins/civicrm $ tar -xf ../civicrm-x.x.x-l10n.tar.gz
If you don't have SSH access and your IP panel does not recognize tar files, you will need to convert it to a zip file.
civicrm-x.x.x-l10n.tar. You should now have a
civicrmdirectory with 2 subdirectories
- Create an empty
- Move the
civicrm2directory (with the 2 subdirectories) into your new
- Zip the
civicrmdirectory and name it
- Now, you can upload
civicrm-x.x.x-l10n.zipand continue with the following steps.
Clear cached files¶
Delete all files in your
In CiviCRM 4.7 and above:
In CiviCRM 4.6 and below:
