问题描述
我站在我在本地制作网站的位置，用作以后演示的产品。
网站内有登录，地址簿，信息中心和活动。 />
我的问题是应该在我的登录脚本中（因为，tilslut.php）突然停止工作100％。它的工作原理是我将从index.php登录，用户名Nicolaj，密码为123789456，但是当必须从下一页，check.php批准时，它会一直报告无效的用户名/密码。之后它应该被发送到页面，forside.php
如果你开始尝试从check.php报告错误时跳转到forside.php没有问题，但如果您在页面forside.php上注销。然后你无法访问任何其他页面。
能帮助我解决问题的人会产生问题吗？ :)
（各页面的代码如下所示。）

I stand in the position where i have made a website locally to be used as a product to a later presentation.
The website within keeps login, address book, message center and events.
My problem is should in my login script (Since, tilslut.php) suddenly stopped working 100%. It works in the sense where i will be logged in from index.php, with the username "Nicolaj" with the password "123789456", but it keeps reporting invalid username / password when it must be approved from next page, check.php, after which it should be send to the page, forside.php
If you start to try to jump from check.php when it reported errors and on to forside.php there is no problem, but if you log out on the page forside.php. Then you can't access any of the other pages.
Someone who can help me with what it is that creates the problem? :)
