Upgrade Guide

You can get new versions of Tarski either by downloading them as a .zip file, or from our Git repository.

Quick upgrade guide

  1. Back up any custom stylesheets, headers etc.
  2. Switch to the default theme
  3. Upgrade WordPress (if required)
  4. Update your Tarski files
  5. Put your custom files back
  6. Switch back to Tarski

Changing themes ensures that Tarski isn’t running while you update your files, and triggers the upgrade routine (visiting the Tarski options page is another way to do this, if you’re just running git pull for example).

Backing up

Tarski is designed to let you modify your site without changing core theme files. However, before you upgrade Tarski, it’s important to back up any custom styles and header images. If you’ve modified any theme files, or added your own templates, you should back those up too. Other changes should be saved in the database, or made via plugins. Backing up your database prior to upgrading either WordPress or Tarski is strongly recommended.


Once you’ve backed up the files listed above, switch to the default theme and delete everything in the Tarski directory. If a new version of WordPress is required for the version of Tarski you are installing, you should upgrade WordPress now. A comprehensive tutorial on updating WordPress is available on the WordPress.org website.

Now download the latest version of Tarski and extract the contents into your Tarski directory, before adding any personalised files back where they should be, and reactivating Tarski. Finally, check your site to make sure everything is working properly.

Living on the edge

If you’re trying out a development version of Tarski from our Git repository, please ensure that you’re using the latest version. New features and bug fixes go in all the time, and testing against stale code helps nobody.
