Some categories are broken: "Load cannot follow more than 20 redirections"

[chrispanag (Christos Panagiotakopoulos)]

After we upgraded to 2.7.0beta2, navigating to some categories is broken. When we try to access a category we get the following errors in the console:

You can try for yourself using the following links:

https://rembetiko.gr/c/-/77/none
https://rembetiko.gr/c/-/159
https://rembetiko.gr/c/ρεμπέτικο-γλωσσάρι/77

Interestingly urls for some different categories work:

Επικαιρότητα - Ρεμπέτικο Φόρουμ
https://rembetiko.gr/c/-/7
Ανακοινώσεις - Ρεμπέτικο Φόρουμ
Μουσική Θεωρία - Ρεμπέτικο Φόρουμ

Our forum is served behind cloudflare and we have setted an origin url (https://origin.rembetiko.gr) for message bus.

We disabled Cloudlfare proxying, but unfortunately the problem persists. For now, Cloudflare proxying is still disabled.

Thanks a lot in advance The work that you do here is wonderful.

We recently merged a change to fix case sensitive slugs in order to fix a different bug. That also had to deal with categories with duplicate slugs and it may have triggered this .

If you open the category 77 and set the slug as nil does it fix it ?

[chrispanag (Christos Panagiotakopoulos)]

You mean like that?

https://rembetiko.gr/c/nil/77

No it doesn’t work

[chrispanag (Christos Panagiotakopoulos)]

Sorry for bumping this - but is there a possible workaround for this? Those categories are still inaccessible…

Thanks again

I’d try to (temporarily) change the slug:

@simon

To fix the issue on my site, I went to the Rails console and ran:

c = Category.find_by(name: 'exemple de catégorie')
c.update(slug: 'exemple-de-categorie')

It might also be a plugin in use in these categories and not in the ones that are working

[chrispanag (Christos Panagiotakopoulos)]

The only non-standard code that runs on some of these categories is the discourse-category-sidebars theme component.

This is the plugin list:

The only non-standard plugin (except for whos-online) is the SealabsOnebox which just produces onebox previews for a website that doesn’t support oEmbed - I can’t think that it can interfere with category loading (especially specific category loading).

@Benjamin_D

I’d try to (temporarily) change the slug:

Thanks for the tip, I will to try update the slugs and I will update this topic with the results.

[Falco (Rafael dos Santos Silva)]

Yes, that the exact thing I meant with setting the slugs to nil @chrispanag

c = Category.find_by(id: 77)
c.update(slug: nil)

Check if the auto slug generation will fix it.
