You are right, I did use Easy Populate and I did reset the ALL Products Master Categories ID's. Then cleared all cache. No help.

Deleted the cat and reset everything and uploaded again with EP. Same result. Don't know where the problem is. No matter what I do it just won't alias the url. What else can I check?

Just for testing, I copied wedding bell box (last item) and changed the title a bit and it does rewrite the url correctly. Guess you can claim your mod is working and the problem is in combo with EP. Still urks the heck out of me...

Any ideas?
