I am trying to access a aspx page from an IIS server. The page contains a registration form. The browser is opening the page, but when I am trying to enter values into the field and want to save it, it displays this 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>
What is the problem, and how do i fix it?
It seems that while saving some error is occuring and you are not getting that exact error.
So you have two options add below code.
<configuration>
<system.web>
<customErrors mode="Off"/>
</system.web>
</configuration>
or Use try catch in your save function and in the catch block put code to write enitire exception as string in a text file and then in text file you will have exact error.
But I would suggest first option.

I am trying to deploy sample website on somee.com using free hosting.
First I published my website as a folder. I already tested on my local machine on IIS 7 in my local machine. That is working fine without any problem.
1. I created new free hosting domain on somee.com, then in file manager ->
2. Then I make a zip folder for my published website folder
3. Then I upload the zip folder and select upload and unzip archives
4. Now this is my root folder file structure
5. I hope it will run the default.aspx file. Then I try to visit my site it throws error like below
Error msg

Note
I created one small default.htm file for testing. If I upload that file. That's working fine.

If I add the default.aspx file as a start up page on web config like below,

Error msg
500 - Internal server error.
There is a problem with the resource you are looking for, and it cannot be displayed.
Here are steps to publish your .net to the server:
Please open your project with Visual Studio tool
On the Solution Explorer windows (which is normally located on the top right hand corner of the VS tool), right click your project and select Publish
Please kindly publish it to a local folder, such as C:\Project
Please just upload whatever files/folders you see on C:\Project to the server via FTP and your site will work fine.
The steps will remain the same. If you face 500 internal server error, please ask somee to check full error message on the server.
In Web.confilg file turn on the customErrors
<system.web>
<customErrors mode="On">
</system.web>
now add connection string carefully .Only change provider connection value
<add name="DBModel" connectionString="metadata=res://*/Models.Model1.csdl|res://*/Models.Model1.ssdl|res://*/Models.Model1.msl;provider=System.Data.SqlClient;**provider connection string**='your database connection path'" providerName="System.Data.EntityClient" />
I am trying to publish a website to make it go live and need to connect to a database. Currently I am using:
<connectionStrings>
<add name="UniversityContext" connectionString="Data Source=(LocalDb)\MSSQLLocalDB;Initial Catalog=RoomAudit;Integrated Security=SSPI;AttachDBFilename=|DataDirectory|\RoomAuditSystem.mdf" providerName="System.Data.SqlClient" />-->
</connectionStrings>
in my web.config which obviously using my local machine.
I've looked online and on here and can't seem to find a clear cut tutorial. Here is the database details:
DATABASE SERVER
mysql4.gear.host
with my username and password with reading and writing permissions.
If someone could point me in the right direction I would appreciate it - I'm also using Entity Framework if that makes any difference?
EDIT:
This is my new connection string:
<add name="UniversityContext" connectionString="Server=mysql4.gear.host;Database=databasename;User Id=username; Password=password;" providerName="System.Data.SqlClient" />
However, when I publish the website I get a runtime error?
Runtime error:
Server Error in '/' Application.
Runtime Error

Console error:
Failed to load resource: the server responded with a status of 500 (Internal Server Error)
IMO, best place for learning to write connection strings is here: https://www.connectionstrings.com/sql-server/
Try this
<add name="UniversityContext" connectionString="Data Source=mysql4.gear.host;Initial Catalog=databasename;User ID=username;Password=password" />
I suggest to create file with .udl extension and test configuration.
It could help you to find proper parameters.
I would like some help in relation to internal error 500 All my application works perfectly on the local server . When I upload via ftp . Web application works by entering a PartialView . Error it gives is " Internal Error 500 " . Does the web server does not support the MVC5 FrameWork 4.5 ?
The error
Internal Error 500
is a generic error message which indicates that the application is having serious problems. The message is generic so as to avoid giving away any sensitive information about the inner workings of your application. However, you can tell the application to provide a more detailed error message by ensuring that custom error pages are turned off: go to your web.config and make sure the mode attribute of the customErrors element is set of 'Off':
<configuration>
<system.web>
<customErrors mode="Off"></customErrors>
<compilation debug="true" targetFramework="4.5" />
<httpRuntime targetFramework="4.5" />
</system.web>
</configuration>
Then try refreshing the application in your browser - it will give you more information that you can use to track down the problem.

This website was working before but was moved over to IIS and now getting this error. The webpage will run locally but not remotely. Perhaps the .NET framework isn't 4.5 on IIS?
This is my Web.config file in asp.net
<!--
For more information on how to configure your ASP.NET application, please visit
http://go.microsoft.com/fwlink/?LinkId=169433
-->
<configuration>
<system.web>
<customErrors mode="Off" />
<compilation debug="true" targetFramework="4.5" />
<httpRuntime targetFramework="4.5" />
</system.web>
</configuration>
In IIS verify that the Application Pool for the website is set to use the correct .NET Framework.
For some reason I can't see any useful information about my errors even though I Changed the customerrors section of the web.config:
<customErrors mode="RemoteOnly">
</customErrors>
All I want to do is be able to see the normal yellow screen of death that shows what is going wrong.
Ever since I tried to upload this site on my local developer PC's IIS, the application has not shown error information.
Whenever I start debugging the application fails immediatly and says, "Server Error in '/' Application." and gives me a 404 http error and only displays the Version of the .net framework and asp.net version.
*UPDATE:
I'm Running this locally on my development pc.
Set the Mode to Off instead of remote only. MSDN explains the different modes here:
http://msdn.microsoft.com/en-us/library/h0hfz6fc.aspx
If you are in RemoteOnly then it will only show the error if you are running it locally.
<configuration>
<system.web>
<compilation debug="true" targetFramework="4.5" />
<httpRuntime targetFramework="4.5" />
<customErrors mode="" defaultRedirect=""></customErrors>
</system.web>
</configuration>
If you want to set your application level exception should redirect to your custom error page, you can do this by going to global.asax file and write the code for redirection in Application_Error method.
For handling all the exception, you just need to write the code for redirection at catch section. Also you can set custom error page for http errors by passing status code.
<customErrors mode="RemoteOnly" defaultRedirect="~/ErrorPages/Oops.aspx">
<error statusCode="404" redirect="~/ErrorPages/404.aspx" />
</customErrors>
