In admin/config/search/redirect/404, I found a lot of invalid url, it's a lot of additional "products" on our url, for example, News/products/products/products/products/products/products; LED-Replacement-Lamps/LED-RGB-Lights/products/products/products/products/products/products/products/products/products; The "NEWS" is our Contents, but "LED-Replacement-Lamps/LED-RGB-Lights/" is 301 redirect I do by "URL redirects”. So I want to know it's the problem of "URL redirect" tool or others?
Problem is in your
pathauto Patterns, go to
admin/config/search/path/patterns1 and check your pattern, it seems you have a pattern that when each time the content edited Url added to your
Url Alias again.
I guess something like this exists there
