My blog: http://hayunperroencasa.com
If I go to Settings - Permalinks and I select, for example "post name", links and pages don't work (appears the horrible 404).
I don't understand why I can change the ugly links (numbers).
I'm really newbie in all of this (I only know about SEO, contents and marketing, I don't know nothing about codes, servers...)
I appreciate help for dummies like me. I'm trying to solve the problems by myself but sometimes I can't.
Thank you.
