Frequently Asked Questions (FAQ)

How many plugins should I use?
There's no magic number, but the fewer plugins, the faster the site and the fewer conflicts. 15-20 good-quality plugins may be faster than 10 poor ones. Test page load time before and after installing each plugin; if the site slows down, deactivate them one by one to find the culprit.
What's the difference between free and premium plugins?
Most free plugins are enough for typical sites. Premium usually adds priority support, advanced features, better performance and more integrations. For example, free Yoast SEO is enough, but Yoast Premium has handy internal linking suggestions and a redirect manager.
Are old, un-updated plugins risky?
Very risky. A plugin not updated in over a year may have unpatched vulnerabilities. It's recommended to find a more actively maintained alternative, or contact the developer before continuing to use it. You should avoid plugins that WordPress.org flags as "Not tested with your version of WordPress."
What do I do about a Plugin and Theme conflict?
Deactivate plugins one by one and see if the problem goes away. If it does, that plugin is the conflict. Try switching to a default theme (Twenty Twenty-Four); if the problem goes away, the theme is the issue. Use WP_DEBUG=true in wp-config.php to view the error log.
