People using linkxxxchange are you getting this error?
 

I keep on getting the error "link already found in database" when I add a url and I can't figure out why that happens, the link is not in the database when that happens.

Yes, i added a site in two of them, two days ago, and i was getting that error, i contacted the admin to be added.

read this on their site:

did you figure out how to solve that problem? it seems like everytime you download and change the file and upload it back it stops working (links.inc.php)
