Problemas con el chat en mi web
Publicado por Erick (5 intervenciones) el 12/04/2014 18:27:15
Hola chicos y chicas he instalado en mi web el chat de anantgarg.com
El problema que tengo es que me funciona perfectamente pero justo cuando cierro la sesion, el chat se queda activado y se pueden mandar mensajes si los dos usuarios estan desconectados, sin embargo cuando los usuarios se conectan no se puede usar el chat, en el server me dicen que el error está en la linea 51 y 122
exactamente esto:
[Fri Apr 11 12:07:40 2014] [warn] [client X.X.X.X] mod_fcgid: stderr: PHP Notice: Undefined index: username in /var/www/vhosts/oshasocial.com/httpdocs/chat.php on line 51, referer: http://www.miweb.com
[Fri Apr 11 12:07:40 2014] [warn] [client X.X.X.X] mod_fcgid: stderr: PHP Notice: Undefined index: username in /var/www/vhosts/oshasocial.com/httpdocs/chat.php on line 122, referer: http://www.miweb.com
os adjunto aqui el codigo con las lineas de error subrayadas para si alguien me puede ayudar con este problemita, gracias y saludos
