I'm an author of a WordPress plugin, WP Static HTML Output. As the plugin is getting more popular, I need help testing it before release to ensure all functionality works.
You will basically follow a test plan that I provide, along with some ad hoc testing to try and break the plugin (better you can break it in development than a user breaks it in production!).
You should be familiar with WordPress and how to install a plugin. Ideally, you will understand how to diagnose issues using the browser console and know where to find error logs on your server. I have a local development environment using Docker and bash scripts which you may be able to get running on your machine for quicker testing.
I'm open to freelancers who don't have any history or experience with freelancing, so this may be a good first easy task to build up your profile. I've freelanced in the past for many years, so can also provide you advice in regards to making a living freelancing :)
