Possible bug: 404 on post type URL rewrites

[EivindFS]

Hey guys,

When I enable URL rewrite on my posts the permalinks throw 404s. When I disable it, they start working again.

I'm not sure if I'm doing something wrong or if there is a bug. I figured I'd report it anyway.

Cheers, Eivind

This is one of the things I've fixed but not pushed in yet. In some cases you need to flush the rewrite rules in order for everything to work.

This is unfortunately not something WordPress does on its own.

Hi ElvindFS you can update and check again

[EivindFS]

Hi!

I just tried with the latest filebase and it still doesn't work.

Eivind

[MarcusDalgren]

Hi Eivind!

Did you save the post type again? The post type has to be saved for the rewrite flush to occur. If that doesn't work can you try going to the Permalinks page in the admin and saving that and see if that solves it?

Marcus

[EivindFS]

Yeah I saved the post type. It doesn't work. Also went to the permalink and saved. No change. (my permalink structure is /%category%/%postname% and category prefix is ".")

Please guide me to a place in the code where I can check that I'm indeed running a filebase with your fix in it.

Cheers, Eivind

If none of that fixes the issue then you probably have conflicting rewrite rules somewhere. WordPress only allows one page type/taxonomy/etc per rule so if two different content types go for the same rule one of them gets the rule and the other one stops working.

Can you post the rewrite rules for the post type in question?

[gleenk]

I have this problem too...

[MarcusDalgren]

Then could you please post the rewrite rules you are using for your custom post types? Like I said in my last post if the rules are set up wrong then the problem isn't Magic Fields, it's the rules you set.

[gleenk]

It gives me 404 with every structure. I also tried to empty the rewrite_rules value field in db but nothing to do. In this moment I've set /%post_ID%/ and htaccess is:

BEGIN WordPress

RewriteEngine On RewriteBase /WPTEST/ RewriteRule ^index.php$ - [L] RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule . /WPTEST/index.php [L]

END WordPress

but even with other combination it doesn't work for me...

[jahberg]

I can confirm this too...I am using /%category%/%postname%/ for permalinks and am getting the 404 errors on Custom post types and regular posts.

[hunk]

this works fine for me http://www.screenr.com/7YWs , have any special settings?

[gleenk]

No special settings for me, clean local installation with only MF installed. 1 Custom Post Type created and 1 Custom Taxonomy (with 3 terms) related to it.

[MarcusDalgren]

And everything worked before you turned on MF? Also does deactivating MF fix your problems?

[gleenk]

I haven't tried it before, but have never had problems before with this WP version, on the same machine. I can't deactivate MF now, I'm using it for a project, what will happen to everything? (is it possible to deactivate and re-activate it without burning everything? if yes, i'll make a try)

[MarcusDalgren]

Yes all your data will stay in the database so when you reactivate it again you get your post types back. We just want to make sure that it isn't something else.

[gleenk]

I've tried disabling MF. Permalink works correctly.

[MarcusDalgren]

Ok. So activate magic fields again and tell us what you set your rewrite rules to on your custom post types. IE go into the magic fields admin and edit your custom post types. Have you ticked the box that says Rewrite and if so, what have you written in the rewrite slug field?

Then do the same for your custom taxonomies and report back here. Ideally if you have set rewrite rules then list your post types and taxonomies and list the rule for each.

Here the screenshots of my actual "not-working" config: http://imageshack.us/photo/my-images/190/mfbufstep1.jpg/ http://imageshack.us/photo/my-images/196/mfbufstep2.jpg/ http://imageshack.us/photo/my-images/577/mfbufstep3.jpg/

[EivindFS]

My htaccess file looks like this:

BEGIN WordPress

RewriteEngine On RewriteBase / RewriteRule ^index.php$ - [L] RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule . /index.php [L]

END WordPress

It's what I always use. You haven't pointed out yet what the changes to the filebase are, smurkas. If you can point me towards the place where I should look for a rewrite rules flush, I can at least double check that I'm using the correct code.

Cheers, Eivind

[MarcusDalgren]

The change was made by @hunk. The change should be in mf_posttype.php on line 555. You should have a function there called update_rewrite and the redirect on line 552 should be pointing to that function.

When I'm talking about the rewrite rules I'm not talking about your .htaccess file. That looks exactly the same for all standard WP installs. The issue is about the rewrite rules WordPress uses internally when figuring out what page/post/taxonomy/etc to load. It's fully possible to set those rules so that WordPress no longer can find pages for example. Basically it's one rule for each post type/taxonomy etc and if there's a conflict somewhere things get messy really fast.

[gleenk]

Has it been fixed? Now it works for me. I just uploaded new files and pushed "save permalinks" button 3-4 times :D

[gnuget]

@EivindFS

Can you confirm to this has been fixed?

[gnuget]

i'm going to close this bug for no activity feel free to re-open it if the bug not was fixed

[kb6673]

I can still replicate this issue with the latest MagicFields available.

[gleenk]

Have you tried to press "save" on permalinks page 2 or 3 times? Try deleting htaccess, come back to permalinks and save 2 or 3 times. If not please write try to replicate the problem step by step for developers ;)

Hi there,

I'm afraid I'm having custom post type rewrite/permalinks problems too.

If I set my Permalinks Custom Structure as follows:

/%category%/%postname%/

Only one of my Custom Post Types works correctly, the other 4 all throw up 404s. If I change the Permalink Structure to 'Default', they all work perfectly.

I've tried deleting the htaccess file, re-saving Permalinks a number of times and re-creating Post Types but no luck so far.

Any suggestions would be greatly appreciated.

Thanks Katri

[katrianna]

Sorry, I should've also mentioned that it makes no difference whether or not I tick the rewrite check box and enter a new slug on the individual Post Types. Cheers.

Hey guys,

I was with the same problem. WP version 3.3.1 using last MF version too.

Suddenly all my new posts were retrieving 404 mitical error. I've been tweaking with all of the possible and findable fixes.

I've resolved my issue by inserting this structure /%category%/%year%/%postname%/ the only difference was the %year% snippet.

"...Now if you wonder why I had the %year% variable in the URL in there was because there have always been issues with WordPress permalink structures that don’t have a number in them, so adding the year solved that problem. "

All best Guys!

I have the same problem using magic fields 2.2 and wordpress 3.7.1.

Just keep getting 404 errors on custom post types and sometimes all my other pages depending on what settings i use.

The only thing that works at the moment is setting the permalinks to default in the wp settings which isnt ideal.

[flodar]

I have the same problem!!

I updated to wordpress 3.7.1 and now there are 404 errors on custom post types.

MF 2.2 | Wordpress 3.7.1.

[blackboxadmin]

It took me ages to work out and after disabling every plugin but magic fields and doing multiple database wipes and fresh installs i tracked it down to having the Rewrite option ticked in one of my custom post types.

I had a custom post type for "services" and one for "team", services didnt have the rewrite option ticked and team did. I was concentrating on debugging the services so never noticed/thought that the problem would be with the team post type.

I finally turned off all rewrite options on all post types (the checkbox below archive slug on the post type options page) and the 404 errors stopped and all was working correctly.

It seems that the rewrite functionality of magic fields 2.2 is broken/has a bug in it. Ticking rewrite in one post type should not create 404 errors for other post types and pages.

With no rewrite options ticked all seems stable now and i can use the permalink structure /%category%/%postname%/ again. If however i re-enable the rewrite option in any post type i first get 404 errors on every page which i can fix by adding the line flush_rewrite_rules(false); to my functions.php file. (not a permanent fix as this seems to be quite a resource hungry function to run on every page load) then all pages work apart from custom post types which continue to have 404 errors.

Solution for now.

Dont use the rewrite option of magic fields 2.2.

[manuelsofia]

I still have the very same problem with version 2.2.1. There's no way to get a Rewrite Slug to work.

[salvatorecapolupo]

same problem here, see i.e. http://www.fidapasoveriamannelli.it/category/articoli/

I'm cleaning the issues if you still have this problem reopen the issue. thanks
