Other useful WordPress plugins
WP Rollback is a great plugin that allows you to rollback versions of WordPress or plugins to previous versions just in case your site gets messed up by an update or plugin issue. This plugin makes that process easy.
Broken Link Checker
Broken Link Checker checks your website content for any missing images or broken links and notifies you if any are found. Although this is a great plugin, just be careful when using it because it can slow your site down a bit. So you may want to use it to scan for missing links and then disable it until you need it again. There may also be some compatibility issues with the most recent version(s) of WordPress.
