Hi Nicolas,
Last time I put the Force canonical URLs on listings to No, generate the URLs and then turned off the Remove products and categories id in URLs at the same time, it didnt work, but this time it worked.
But I have another problem, (please see sidebar.png image) I have the sidebar and those came from Products > Categories. I customized the URL but when the two options above are turned off, my sidebar doesnt follow the customized URL I put (see cutom-url-cat image for reference). Please see not-custom-url-cat, that is the URL that's generating, which is not right.
I hope I provided enough screenshots for I really need to finish and solve this problem right away. It always takes you 24hrs to reply and my time is wasting.
I have attached (final-sef-options) another image for the configuration.
Thanks.
