Frequently Asked Questions
How many plugins can I install?
There’s no hard limit, but quality matters more than quantity. 20-30 well-coded plugins are fine. Poorly coded plugins cause problems regardless of quantity.
Do inactive plugins affect performance?
Inactive plugins don’t affect front-end performance but still pose security risks if not updated. Delete plugins you don’t use.
How do I know if a plugin is safe?
Check last update date, active installations, reviews, and developer reputation. Avoid plugins not updated in over a year.
Can plugins break my site?
Yes, incompatible or poorly coded plugins can cause issues. Always backup before installing new plugins and test on staging first.
