M2 - All category pages are only 404 - tried several solutions

[tabstop]

Hi,

on my first try of the category pages i get only 404 whoops errors.

I have Magento 2.1.5.

I imported about 20000 products in my single shop. The products are available in the search. But now I tried the category tree from Codazon Megamenu. All links go to 404. Thats an example:

http://domain.com/catalog/category/view/s/test123/id/972/

http://domain.com/kinderfahrzeuge/laufrader.html

I tried several things:

- magento indexer:reindex

- magento setup:di:compile

- cleared var/cache,var/generation,var/pagecache,var/di

Maybe its a problem that I have more than one root category?

Now I dont know what I can do to make it work. Google was my friend but I only found the named methods.

What can I do?

Thank you

Regards

Hello,

You have url rewrites enabled?

[Saggitator]

You need to check the following things -:

1) Enabled category is set to YES

2) Products are assigned to the category

3) URL key is correct

4) Re-index has been run php bin/magento indexer:reindex

5) Caches are cleared
