Hi, When I view the http log for serweb directory, I find that there is any error (not PHP notice): [error] [client 218.189.163.22] File does not exist: /home/officehk123.vttsys.com/html/favicon.ico it seems that favicon.ico is necessary. But there is no such file. I create one for myself. I know that it is an image. The error message disappears afterwards. Have any of you encountered this error before? Why is favico.ico needed? Thomas
