Hi,
I am Kapil Samadhiya. I am also facing same issue. I am using DotNetNuke-4.5.3 version. Earlier my site was running, but its stopped running suddenly and giving this error. May be it is because of uploading any new module, But I have tried after removing DLLs of that module. Still site is not running.
I am also confused because its giving error of "Object reference not set to an instance of an object. "
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>
</configuration>

while accessing through localhost, But If I am accessing this site from outside (internet) then its giving error of "Runtime Error"
