Nybegynder: login fejl

Vi kan ikke se hvad fejlen er, før du ændrer i web.config filen, som der står i din fejlbesked.

Den ser således ud:

Prøv at erstatte dette:

<customErrors mode="RemoteOnly" defaultRedirect="Secure.aspx">
            <error statusCode="403" redirect="NoAccess.htm" />
            <error statusCode="404" redirect="FileNotFound.htm" />
        </customErrors>

Med dette
<customErrors mode="Off"/>

Så kan vi se hvad fejlen er.

Kører dit login script mod en database?

Hej

<customErrors mode="Off"/> er indsat istedet for og ja den kører imod en database. Jeg har anvendt wizarden i Visual Web Developer 2008.

Fejlen efter udskiftning af CustomErrors:

---
erver Error in '/' Application.
Runtime Error
Description: An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine.

Details: To enable the details of this specific error message to be viewable on remote machines, please create a <customErrors> tag within a "web.config" configuration file located in the root directory of the current web application. This <customErrors> tag should then have its "mode" attribute set to "Off".

<!-- Web.Config Configuration File -->

<configuration>
    <system.web>
        <customErrors mode="Off"/>
    </system.web>
</configuration>


Notes: The current error page you are seeing can be replaced by a custom error page by modifying the "defaultRedirect" attribute of the application's <customErrors> configuration tag to point to a custom error page URL.

<!-- Web.Config Configuration File -->

<configuration>
    <system.web>
        <customErrors mode="RemoteOnly" defaultRedirect="mycustompage.htm"/>
    </system.web>
