Automatic Installation
Installing this plugin automatically is the easiest option. You can install the plugin automatically by going to the plugins section in WordPress and clicking Add New. Type "WooCommerce Change Product Author" in the search bar and install the plugin by clicking the Install Now button.
Manual Installation
To manually install the plugin you'll need to download the plugin to your computer and upload it to your server via FTP or another method. The plugin needs to be extracted in the
wp-content/plugins
folder. Once done you should be able to activate it as usual.
If you are having trouble, take a look at the
Managing Plugins section in the WordPress Codex, it has more information on this topic.
After activating the plugin you will be able to change the author assigned to a WooCommerce product by editing the product in the WP dashboard. See screenshot for details.
If you do not see a place to change the author, check the screen options and make sure that 'Author' is checked. See screenshot for details.
Please note that WooCommerce must be installed and activated for the plugin to work.
