How to Install WordPress Subscription Plugin + Top Free Plugins to Use
Ivailo, you already wrote an article about how to install must have WordPress plugin, how this is different from the one here?
To tell you the truth, there aren’t a lot of differences during the installation process. No matter which plugin you are going to install, the steps are pretty much the same – you download the plugin, upload it from inside your WordPress dashboard, activate it and configure it. Or if the plugin is available inside the WordPress.org repository, you can install it straight from your WordPress dashboard. That’s basically it.
