Dear Sir/Madam,
I have installed dotproject on a linux server
after entering the user name and password and
clicking on login ,I got a blank page and I have to
click on the go button of my IE two times and after that
the site will be displayed.
Also this happened when I want to save some datas
such as project ,tasks , ....
I don't have this problem on the Windows servers.
My server information is :

Operating System Linux
Apache Version 1.3.33 (Unix)
Kernel Version 2.4.21-15.0.4.EL
PERL Version 5.8.1
PHP Version 4.3.9
MySQL Version 4.0.22-standard


I would be appreciate your help and support.
Thanks
Arma

What do you mean "I don't have this problem on the Windows servers." ? Do you have dotproject installed on a Linux and a Windows server?

Have you tried it using another browser or computer to see if the problem happens elsewhere?

Does the windows box also use php 4.3.9?
There were some problems that went away after 'downgrading' to 4.3.6.
