requested URL /archive/css/ was not found on this server

For those who have changed their permalinks, gotten into a bind, and are not programmers but just want your blog to work …

I did not find the fix here in the codex, but googled and found it on this site –>> https://blog.taragana.com/index.php/archive/wordpress-tip-on-permalink-options/

I did as suggested with the below

Structure: /index.php/archive/%postname%/
Catagory base: /index.php/category

I tried it without the index.php but the problem came back.

cat

Yep, that would mean that your server does not have mod_rewrite, and the information was in the Codex. See:

Yup, looks like it was in the Codex all the while, but it was greek to me. I did try various other suggestions in the Codex with no luck, so after two days I used the handy dandy google. No matter how one gets there, all I care is that it works.
