404 and permalink structure changes

under a multi site install, for one site I have changed the permalink structure to

/%category%/%postname%/

Sidenote – That’s a TERRIBLE permalink structure. It’ll slow your site down. Read https://ottopress.com/2010/category-in-permalinks-considered-harmful/

On the site you’re having this issue, try changing the permalinks to anything else (like default ?p=123) and if that works, pick one of the standards (like yyyy/mm/dd/postname) and see if THAT works.

Thank you for your answer

I now know it is a terrible permaling structure, I wish I knew it before (I have 2 main sites using this structure, each site has several 100’s posts and I don’t want to loose SEO juice when I will move them to network.. but that is another story)

for my testing site

if I try with
/%year% /%postname%/

webbrowser prints
Erreur 310 (net::ERR_TOO_MANY_REDIRECTS) : Trop de redirections

if I try with
/%post_id%

I have a 404

if I do:
%year% / %monthnum% /%day% /%postname%
then it works

if I do :
?p=%post_id%

then it works

so my understanding is that it must come from the url rewrite, hence why I have added my htaccess

but then I’m totally lost on what can I done wrong

cheers

I’m quite confused cause if I well understand with Multisite you only have to change the permalink structure to the site option page

https://mydomaine1.com/wp-admin/network/site-settings.php?update=updated&id=3

That’s not correct, actually.

Go to subdomain.domain.com (or whatever – mappeddomain.com/ ) and go into wp-admin -> General Settings -> Permalinks ?? That’s the same. Change it there and hit save.

YEAH you rock Ipstenu

when configured from the very site, it works !! incredible..

so it means there is a difference between

https://domainemother.com/wp-admin/network/site-settings.php?id=2

https://domainedaughter.com/wp-admin/options-permalink.php

for my knowledge, when should have change data from site-settings.php?id=2

Thank you again

Steffy

Well I’m 99% sure the difference is that you’re not pressing ‘save’ on the daughter, and thus it doesn’t actually flush the rewrite settings.

I guess you mean the on the mother (site-settings.php?id=2)

I’mp pretty sure I do, I have the message ‘Site options updated’ on top of page after pressed ‘save changes’

I have done a re-test

and it has the same problem

if I change from site-settings.php?id=2 to /%category%/%postname%/ (I know I must not, just for test) I get a 404

if I change from from options-permalink.php and have the message ‘Permalink structure updated.’
then it works

so it looks like on the mother it doesn’t actually flush the rewrite settings when I change from site-settings.php?id=2

is that a normal behaviour, or is there a ‘problem’ in my install? if a problem, how can I investigate and solve it?

Thank you in advance

No I mean …

Okay, you have to change the permalinks ON the site you want to change the permalinks. If you want to change daughtersite, you go to daughtersite.domain.com/wp-admin and do it there.

DO NOT change it in the network area.

ok Cristal clear Ipstenu

may I ask them why this field (permalink structure) is an editable field on the network area? if it should not be changed from there, why not a non editable field, so that sup admin can see the info right from his admin panel but can’t mess with it (such like I did)

is there other fields in this network area, that are editable but MUST NOT be modified from there but rather on the daughter site

Thank you in advance, this will help me to screw less things

Mmm.

Well it’s there because you CAN change it there, but it doesn’t reset the permalinks (i.e. flush the rules on the server). I’m not sure if that’s a bug or not, though. I’ll play with it more and see!

Pretty much everything in that Options page is ‘Don’t change it unless you HAVE to and even then, not unless you know what you’re doing.’

There’s an options page in regular WordPress (hidden) and you can shoot yourself in the foot there.

Thank you for the answer Ipstenu, as of now I will make those changes from the daughter site admin thank

Thank you to better me on my practise, I’m there for this
