Product's name refuses to change

Hi,
In the first place the names of my products were their serial number,
Now I want to change them to more 'pleasant' names...

I changed in the admin panel successfully (Using Apsone) - I can actually see the desirable names in the admin area.
BUT for some reason in the front end, the visitors still see the old names.

I want to mention also that in the past I did the same for few categories and didn't encounter this problem.

I use opencart V1.5.1
e.g. of a problematic product: http://noajewelry.com/%20Amazonite%20Je ... uct_id=281
e.g. for when succeeded http://noajewelry.com/larimar-jewelry-c ... uct_id=119

Thank you

You should not use spaces in your SEO Keywords for URLs for starters.

not sure what SEO Keyword generator your are using that is putting .html in the keyword, allowing spaces and still adding product_id to the end, but I would look for a different mod if I were you.
