How to create multiple site in Kentico 8.2

Hi,

you need to setup new domain for new site. If you want to run new site under current domain you need first to stop current site and play new site. This all needs to be done under sites.

yes i did exactly first i stopped my previous site and then i started my new site but the problem is not resolved.....

If you plan to run the site under the same domain name then yes, you need to do what Petar suggested. If you plan to have multiple domains running at the same time, you need to have a license key for each domain. What I typically do is restart the whole website after I do a start and stop like that just to make sure things are cleaned up. You can do this in the System app.

hiii...Brenden Kehren i did as you told.i did all option which is in system app(clear cache,Restart application,clear performance counter,clear unused memory,Restart window services ) and also restart the whole website.but the problem is not resolve. and can u please tell me why this is happen...?

Have you tried a different browser? Also, are these two site completely different? Are you somehow sharing the same master page or other templates?
