404 error with wrong mix of product and category

Hi,

In the Joomla backend I can see that there are 404 errors like this one :
www.123soep.nl/disposables/product/18-cu...-21-x-175-ml-mosterd
This is a non existing url because is should be :
www.123soep.nl/cup-a-soup-caterpacks/pro...-21-x-175-ml-mosterd

For some reason I did something wrong in my configuration but cannot find out what.
The disposable category does not contain products like this at all.

Any tips are more than welcome.
Nico

Hi Nicolas,

I see the error in the Joomla backend under Components > redirects and I tried several different ways to get this error but still no luck.

I was thinking it was coming from going from the main menu > Producten > Disposables and then click on one of the related items below but unfortunately I cannot recreate this.

I have disabled the redirect plugin to see if this changes anything but I only get the errors in the redirect component at this moment.

If I get the error I will certainly update this post asap with the links that caused it.

Thank you.
Nico
