I have my ASP.NET application hosted on godaddy server. This appliation is running perfectly fine

from one year, but from yesterday following error is coming when I try to open the application in

browser not even the login page is appearing.

Description: The application attempted to perform an operation not allowed by the security policy. To grant this application the required permission please contact your system administrator or change the application's trust level in the configuration file.

Exception Details: System.Security.SecurityException: Request for the permission of type 'System.Security.Permissions.SecurityPermission, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.

I didn't make any update or did not change any setting.

Please help me as early as possible.

As the error says, contact GoDaddy support. It's a configuration issue.

Looks like your application attempts to load something that requires "full trust". Thus, this is most likely some trust issue.

Solution 1

The exception itself states that change the application's trust level in the configuration file. Have a look at ASP.NET Trust Levels and Policy Files and How to resolve Security Exception. This exception can be due to lack of proper trust level in the machine.config file on the server.You can contact the administrator for further assistance.

Thanks for your reply Rohan Leuva, actually I google a lot before posting this question, the scenario is this, my application was perfectly working day before yesterday but from yesterday even login page is not appearing. I contact godaddy and according to them they didn't change any configuration.

I am actually very confused that why this trust level issue coming from yesterday? why this issue not coming before because everything is same and i did not add any other reference in the project.

I am also using devexpress controls in this ASP.NET project. If anybody has any idea regarding this issue please help me out. I am posting again the whole error again.

If you can't bother reading documentation and contacting the right support center, then stop coding...

and you stop doing F******* comment

No need to get rude. This problem will need to be resolved by the administrators of the hosting site. The way to get to the administrators is via the Support people. If you want to shout at someone, shout at the people responsible for the problem, not the person that told you how to resolve it

some people are going as over smart, my question is that i want to run my website on medium trust level, how i can do

you know that

We can't answer that without a lot more detail - use the "Ask a Question" link to post your own question. Include as much detail as possible - including details of your config
