Community Q&A
Why is my WordPress site suddenly slow?
Sudden slowness is often caused by a theme conflict, a recently installed plugin, or server-side resource limitations from your hosting provider.
How do I test if my theme is slowing down my site?
Switch to a default WordPress theme like Twenty Twenty-Four. If your site speed improves significantly, your previous theme was likely the cause.
Do too many plugins slow down WordPress?
Yes, excessive plugins can increase database load and front-end assets, though the quality of the plugin code matters more than the total count.
