Course catalog points to “Page not found”

@pdoc,

Thanks for all the information here. I took a look at your site and all of your course catalogs (and individual pages) appear to be functioning. I’m not really that familiar with WPML (it’s on my enormous backlog to take their plugin compatibility courses and apply as an officially supported WPML plugin but I simply haven’t had the time to do that yet) but it seems like your issue maybe is resolved?

I’m guessing that the issue is a permalinks issue and once the translations are in place all you need to do is (maybe) flush them and you’re good to go

If you still need help please let me know,

Hi Thomas,

My issue is not solved, unfortunately.
The reason why you saw everything working, is possibly that your browser has English as the default language (you would see the UK flag in the menu).
In fact the issue is that the catalog works only in English ??
If you try to switch to Spanish,for example and go to “Catalogo cursos”, and then click on any course, you will get the “Page not found” (“Vaya! Esta página no se encuentra!”)
It is interesting, though, your comments about the permalinks, but I am not sure I understand the technical meaning of your advice, could you please give some more detail?

Thanks a lot!

@pdoc,

I see, I checkend the catalogs themselves in different languages but I didn’t check the courses because I didn’t realize you were having issues on the courses themselves.

So re permalinks:

WP Stores permalink data in the database (WPML probably hooks into this) so when you translate “course” (the URL slug for a single course) to “courso” that new slug won’t be present in the database so you’ll need to “flush” the permalink data so that the new URL slugs will be available when someone requests them. This caching causes the 404s immediately after applying a translation and once flushed you shouldn’t have to mess with it again (unless you update your translation for that slug).

Flushing is easy: https://lifterlms.com/docs/how-to-flush-wordpress-rewrite-rules-or-permalinks/

Give that a shot, maybe it’ll resolve the issue.

Hello Thomas,
Finally I think I could solve it.
It has to do do with a combination of WPML plugin, permalinks, and how this affected my LifterLMS installation.

I want to thank you for your willingness to help, besides not being necessarily a LifterLMS problem. I appreciate that you could find the time to give advices in a timely manner.

So now I’m updating this to leave a record of what I did, because I understand that WPML is a popular multilingual plugin, and my issue may be experimented by others:

SYMPTOM:
LinfterLMS and courses correctly functioning in a single language site.
Then WPML plugin is installed to configure additional languages.
Courses (they must be a special kind of post, I guess) can then be translated in other languages -just like regular post do.
At this point, the course catalog shows a list of courses that have been translated for any given language, but if you click on a specific element, the course description is not shown, a 404 page is presented instead.
The only course catalog that allows to open individual courses details is the English one, even if the original language of the site (so the language in which all courses had originally been created) is another one.

SOLUTION:
I did a combination of the following:
– Install the additional “WPML sticky ilnks” plugin
– In the admin panel go to In admin panel: Settigs->Permalinks, then “Common Settings” and select the “Plain” radio button.
– flush the permalinks by clicking save

This seems to have returned the situation to normality.

@pdoc,

Thanks for figuring this out and posting your findings!

Thanks, very useful info fixed my problem too.
