I have SMF 2.0.1 release.
Installation Nchat no problem + chmod check.
I can post and read message on Nchat.
But this message appear every time :
"The ./nchat/index.php is now unavailable! Please contact admin forum about this issue!"
When i post another time, no pb, and a second after, the message come back...
On Chrome or Firefox, the same.
Thanks a lot !
