Can I Install Outdated WordPress Plugin?
Sometimes you can find a plugin that hasn’t been updated for a while or hasn’t been tested to make sure it’s compatible with the latest WordPress version. It always depends on the plugin whether it’s safe to install or not. Some outdated plugins are completely safe, others aren’t.
It’s better to check whether you can use a plugin safely. First of all, check its reviews and rating on the WordPress Plugin Directory. Then you should also check the plugin support page. There all the issues that the users faced will be displayed.
You can also check the plugin development page. There you’ll see how active the developer is and how often he updates the plugin.
If you think that the plugin is safe to use, don’t rush to install it on your live website. Instead, try to test it on your staging website first. This is a test version of your website, and even if something goes wrong, its changes won’t affect the live site.
