how to remove 200909251309 in end of url

Hi

I have updated my website from version 1 to version 1.5 joomla. My old seg urls didnt have any date in the end.

Im a bit worried how the search engine will responfd when my urls got a new "extension"

looks like this
/section/category/articlename-200909251308/

Set "Unique item" to "No" in your SEF Advance configuration.

thanks mate
