Thank you, now it's working fine.

It's not working, I get the following errors: Route "product_rule" with rule: "{rewrite}-{id}.html" needs a correct delimiter Route "category_rule" with rule: "{rewrite}--{id}" needs a correct delimiter Route "supplier_rule" with rule: "{rewrite}__{id}" needs a correct delimiter Route "manufacturer_rule" with rule: "{rewrite}_{id}" needs a correct delimiter Route "cms_category_rule" with rule: "/category/{id}-{rewrite}" needs a correct delimiter

Thank you, I will try it again.

The same way as in Prestashop?

I don't understand what you mean by "That should preserve your back links".

I know but I don't want to loose my backlinks but please let me know if you have a better solution.

I'm afraid they are in the links, https://www.speciaal4kids.nl/poppenwagen-maja-von-hohenzollern-919.html I also had a problem with some categories in het menu, some did well and some didn't work so I restored my shop.

Just did the migration from ps 1.6 to thirty bees and all went well but as the breadcrumb and id's are different my backlinks are getting a 404-error and Google doesn't like that. Can anyone tell me what to do?
