Easy Theme and Plugin Upgrades


WordPress has a built-in feature to install themes and plugins by supplying a zip file. Unfortunately, you cannot upgrade a theme or plugin using the same process. Instead, WordPress will say « destination already exists » when trying to upgrade using a zip file and will fail to upgrade the theme or plugin.

Easy Theme and Plugin Upgrades fixes this limitation in WordPress by automatically upgrading the theme or plugin if it already exists.

While upgrading, a backup copy of the old theme or plugin is first created. This allows you to install the old version in case of problems with the new version.

Attention: Version 2.0.0 changed the functionality of the plugin. You are no longer required to select « Yes » from a drop down before the theme or plugin can be upgraded. The need for an upgrade is now detected automatically. So, if you are used to the old functionality of the plugin, do not be concerned about the absence of upgrade details on the theme and plugin upload pages. Simply upload the theme or plugin as if you were installing it, and the plugin will automatically handle upgrading as needed.


  1. Download and unzip the latest release zip file
  2. Upload the entire easy-theme-and-plugin-upgrades directory to your /wp-content/plugins/ directory
  3. Activez l’extension via le menu « Extensions » de WordPress.


Why does the plugin no longer show the drop down to select « Yes »? Is the plugin broken?

Starting with version 2.0.0, this plugin no longer requires that a drop down is used to indicate that an upgrade is to be performed. The plugin now can determine if an upgrade is required automatically. This change not only streamlines the process for many users, it also fixed compatibility issues that some users experienced with older versions.

I used this plugin in the past and recently on a WordPress 6.4.2 installation without problems. It does what it is supposed to do.

Add plugin results in « The plugin does not have a valid header. » Everything about this theme is low-grade and they are slow to update. I have over 100 themes and this is the only one that has continual update problems and even the recommended way of updating has problems. Pfft
