How to Restore Your WordPress Site
Using a plugin is the easiest way to revert your website to a previous version.
Restoring Your Website With a Plugin
From your WordPress dashboard, click on Plugins.
Click on Installed Plugins.
Find the relevant backup plugin. When you click on it, you should see one or more Restore options.
Note: You’ll only be able to do this if you’ve already installed a plugin. If you have, you can restore all aspects of your site to a previous version that worked better. The backup options should be listed by the date and time they were originally saved
Installing and Activating Plugins
However, for the backup plugin to work, you install it before something goes wrong.
First, you should know how to install a plugin.
After that, you’ll want to activate a plugin.
Once that’s done, you can follow your specific plugin’s instructions to back up your website either automatically or manually. That way, previous versions will be there when you need them.See All WordPress Guides
