Most seasoned WordPress admins are aware of the simple plugin installation process and they can skip this section safely.
Installing from WordPress.org Repository (Works only with Standard Edition)
Go to Plugins section of your Dashboard and click Add New button on the top. In the new “Add Plugins” page click on the “Search Plugins” box and type “RegistrationMagic”. Hit Enter on your keyboard. A new page with search results will show Standard Edition of RegistrationMagic. Click “Install Now” and follow the instructions.
Installing Zip file from WordPress dashboard (For both Standard and Pro Editions)
Go to Plugins section of your Dashboard and click Add New button on the top. In the new “Add Plugins” page, click on Upload Plugin button. A new page with “Choose File” button will appear. Click on the button and your browser window will open. Find the zip file you have downloaded and select it. Now back on the page, click “Install Now” button. Once you see success message – Plugin installed successfully – there will be a link “Activate Plugin below it. Hit it and you are ready to go!
Upgrading from Standard Edition to Silver Edition
If you already have a version of the plugin installed, and you are installing Pro Edition or a zip file with new version of the plugin, make sure you deactivate the existing plugin before installing from new file. Once new plugin file is installed you can safely delete old version/ Edition without losing any data. If you do not deactivate old version you will receive this error: Plugin could not be activated because it triggered a fatal error.
