Everything works well and I had friendly URL on my website until I tried to work with Advanced SEO plugin.
After changing some titles things I got 404 error for products. Even after removing it from module I get the same issue.
For catalog and other pages everything works fine. Only product pages got this issue.
Cache is off
Switching to debugging mode with switching off all 3rd party plugins doesn't help me to solve this issue.
Do you have any ideas how to treat this?
Here is a link to some page that give me 404 error
