Frequently asked questions (FAQ)
WordPress suddenly slow – fastest check?
Test PageSpeed Insights. Then: enable caching plugin, disable newest plugin (conflict?), PHP 8.2 in Plesk.
Which cache plugin for WordPress?
LiteSpeed Cache (if LiteSpeed), WP Rocket or W3 Total Cache. One plugin is enough – not multiple at once.
Does Cloudflare help slow WordPress?
Yes – CDN caches static assets. Origin must still be fast. See Cloudflare DNS + website performance guides.
