How can i redirect between www and non www

slem.gq (I suppose this is the domain)

I would not change anything

it’s all on your own responsibility

  1. First you have to convince yourself that in your Cloudflare exists www (dns section)

Capture


2. remove any existing redirect
3. you need to set up wordpress to use www


4. Pray that nothing goes wrong !

such action can break WP
very often happens that some URLs (pages) in the database remain in the old address (plugins and themes too)
