[niconet2001]

Hello all, I am new and I have a small problem. Here, I installed Horde (the last version), I think well of having configured it and when I connect me on the Web page, I obtains only white pages without errors. I do not understand any more, somebody to help me little. I have the last version of PHP and of mySQL and my server HTTP is Visnetic Website 3.5.

Thank you in advance
