Server Error in ‘/’ Application. ASP.NET

Greeting,

I developed a website using ASP.Net 3.5 and C#. It is working good with Visual Stdio 2010.
I uploaded my website to my domain under the public folder.

First time I lunched my website for testing (http://wecoders.com/Habib_cuizine/Gallery.aspx)
I would revive (Server 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
tag within a
“web.config” configuration file
located in the root directory of the
current web application. This
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
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>

To fix this error I added to the webConfig file inside tag:

> <customErrors mode="Off"/>

After that when I lunch the website I would receive a new error as listed bellow:

Configuration Error
Description: An error occurred during the processing of a configuration file required to service this request. Please review the specific error details below and modify your configuration file appropriately.

Parser Error Message: It is an error to use a section registered as allowDefinition=’MachineToApplication’ beyond application level. This error can be caused by a virtual directory not being configured as an application in IIS.

Source Error:

Line 35: ASP.NET to identify an incoming user.

Line 36:         -->
Line 37:         <authentication mode="Windows" />
Line 38:         <!--

Line 39: The section enables configuration

Source File: 10.0.40.35wecoders.compublichabib_cuizineweb.config Line: 37

Please advice how to fix this error and how configure my website which developed using Visual Stdio 2010 to be published in the internet.

Regards,

Thank you for visiting the Q&A section on Magenaut. Please note that all the answers may not help you solve the issue immediately. So please treat them as advisements. If you found the post helpful (or not), leave a comment & I’ll get back to you as soon as possible.

Method 1

The key information in this error is this line:

This error can be caused by a virtual
directory not being configured as an
application in IIS.

In IIS, you can have several applications, but they must be configured as an application. Generally, when you create a web project it maps directly to an IIS application.

Check with your hosting service on how to create an IIS application for your web app.

Edit – added
If this is on your server, you can set this up yourself following the instructions in @Frazell Thomas’s answer. He beat me to finding that link. To save yourself some reading, you should be able to focus in on the Creating Virtual Directories and Local Web Sites section.

Method 2

• right-click virtual directory (e.g. MyVirtualDirectory)
• click convert to application.

Method 3

Have you configured the virtual directory as an ASP.NET application for the right framework version?

See IIS Setup

Method 4

Look at these two excerpts:

I uploaded my website to my domain under the public folder.

and

This error can be caused by a virtual directory not being configured as an application in IIS.

It’s pretty clear to me that you did exactly what you said you did, and no more, i.e. you transfered the files to the web server, but nothing else. You need to configure that public folder as a virtual directory in IIS as the error is telling you, or it’s just not going to work.

Method 5

Looks like you have <authentication mode="Windows" /> in your web.config file but your hosting provider won’t let you use that. Just remove that line.

Method 6

I got the same problem and my solution was to remove webconfig file from the directory.. then it works..

Method 7

http://www.velocityreviews.com/forums/t123353-configuration-error.html

If you want to use inetpub/wwwroot/aspnet as your application, remove this
line :

Line 26:
and any other lines which define MachineToApplication beyond application
level

If you want to use d:inetpubwwwrootaspnetbeginchapter02 as your
application,
create an IIS Application which points to
d:inetpubwwwrootaspnetbeginchapter02

---

maybe you can refer link above.
For my application, my web.config store in d:inetpubwwwrootaspnetbeginchapter02
and when i move the web.config to d:inetpubwwwrootaspnet and the problem is solve.
Please check also does your application have two web.config file.

Method 8

Looks like this is a very generic message from iis.
in my case we enabled integrated security on web config but forgot to change IIS app pool identity.
Things to check –

• go to event viewer on your server and check exact message.
• -make sure your app pool and web config using same security(E.g Windows,integrated)

Note: this may not help every time but this might be one of the reason for above error message.

Method 9

I have the same issue, my application was running on amazon vps, lately i found that bin folder had multiple copies of dll's …
After removing those copies of dlls like entityframework(copy1).dll, errors were gone….
May be some one will get help…cheers

Method 10

Removing the web.config-file from the IIS Directory Folder solves the problem.

Method 11

Try removing the contents of the <compilers> tag in the web.config file. Depending on who you’re hosting with, some don’t allow the compiler in production.

Your application is trying to compile when it is called and their servers won’t allow it.

Method 12

This wont necessarily fix the problem…but it will tell you what the real problem is.
Its currently trying to use a custom error page that doesn’t exist.
If you add this line to Web.config (under system.web tag) it should give you the real error.

<system.web>
    <!-- added line -->
    <customErrors mode="Off"/>
    <!-- added  line -->
</system.web>

Method 13

If your project is linq with Sql Database.
Then Simply Check your System Services and Start sql Server Agent Service.
Now your problem is solved.

Method 14

Just check connectivity between SQL And your App (if you used SQL)
