The current custom error settings for this application prevent the details of the application error from being viewed remotely

I've deployed the application on Server (HostGator), and on Preview it gives me following error
Server Error in '/' Application. 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: This configuration section cannot be used at
this path. This happens when the site administrator has locked access
to this section using from an
inherited configuration file.
Source Error:
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.
Source File:
D:\InetPub\vhosts\accleague.org\admin.accleague.org\web.config
Line: 24
But when same application deployed on another Server, it runs smoothly on 1st try.
Tried every possibility mentioned on internet but unable to resolve the issue.

Could not load type 'PrintMan.MvcApplication'

I am making my very first asp.net project live and running into what I assume is configuration options. Note that there are similiar threads on StackOverflow regarding this but I have already gone through those answers but no success.
The project is working perfectly in my dev environment but on the production server it fails to work. I have restarted IIS, I have currently only this site in the config and the namespace is correct.
Having limited experience in this I am hoping someone can explain what the underlying issue is :)
Server Error in '/' Application.

Could not create type in Web service (C#)

I've putted my Web Service to host (somee.com). My code runs fine on local machine, but when i try to run it on host, i got error and i dont know why. Anyone can give me the way to fix this problem?
Description: An error occurred during the parsing of a resource required to service this request. Please review the following specific parse error details and modify your source file appropriately.
Parser Error Message:

Source Error:
Line 1: <%# WebService Language="C#" CodeBehind="VehicleAPI.asmx.cs"
Class="WebService.VehicleAPI" %>
Source File: /WebService/WebService/VehicleAPI.asmx Line: 1

You might have to do this,
Right click on the web service and select "View Markup" and change the markup to use the correct namespace:
<%# WebService Language="C#" CodeBehind="VehicleAPI.asmx.cs" Class="WebService.VehicleAPI" %>

asp.net parser error - Could not load type 'Umbraco.Web.UmbracoApplication' after moving umbraco to shared hosting

I just moved an Umbraco 4.0.3 application to a shared hosting, with asp.net 4 classic mode.
i have copied all the source to the new location, uploaded the database and changed the connection string.
But i get the following parse error:
Parser Error Message: Could not load type
'Umbraco.Web.UmbracoApplication'.
Source Error:
Line 1: <%# Application Inherits="Umbraco.Web.UmbracoApplication"
Language="C#" %> Line 2:
Source File: /global.asax Line: 1
Here is a snapshot of the error page

I had to rename the project locally from using 'umbraco' to resolve the same error.

Server Error in '/' Application on web site Hosting on internet issue C# aspx

I have a Website that is hosted on WWW/internet, when I tried to open abcxxx.com/WebApplicationASP/login/login.aspx its showing below error;
Server Error in '/' Application
<%# Page Language="C#" AutoEventWireup="true" CodeBehind="Login.aspx.cs" Inherits="WebApplicationASP.Login.Login" %>
Same Web site hosted on my local PC in IIS showing no errors. Its working fine.
I have googled and found I need to change CodeBehind to CodeFile:
now I got the below Error:
Parser Error Message: The file '/WebApplicationASP/login/Login.aspx.cs' does not exist.
Is that means I have to add C# source files too ?
I published website in my localPC using IIS at filesystem C:\inetpub\wwwroot\WebApplicationASP same file structure I have put on my www hosting site? Do I need to do anything more to make it work ?
Thanks,
