    500 error 7.4.1 backend

    Hi,

    I get an 500 - Internal server error, when i try to login to the umbraco backend. The frontend part of the website is working.

    What am i missing? Do i need to install something mvc related cause its 7.4.1 version?

    Nope, none what so ever.

    I have other sites running, but none as new as 7.4.1

    The newest besides this is 7.2.4

    ... and what about the IIS logs?

    Do they give you any useful information?

    Nothing there.

    Could it be that i need a newer .net version when using 7.4.1?

    I don't know about that, but if the front-end part is working, then maybe not.

    What version of .NET are you running?

    You may need to delete a few caches, or run an IISRESET on the server (or recycle the application). In fact, you could check your application pool on the server and see which version of .NET it's running.

    I've had a few 500 internal server errors, sometimes caused by trying to register dlls more than once in the web.config (where I've merged them and the same code got replicated), or by trying to run 32bit code in an application pool that doesn't allow it. It might be that you just need to reset the permissions on the Umbraco folder.

    If you try the app on the server itself, do you get any more information, because really, the 500 error can be caused by any number of issues.

    I've got version 7.5.2 running on .NET 4 running fine.

    You seem to be running the website itself without any problems.

    Without seeing an error it will be pretty hard to track down.

    Can you fire up the Web Developer Tools either in IE or Chrome, then open the Network tab, start recording, and reload the umbraco backend. You may see an error there that can help track this down, e.g. files it can't reach...

    Problem solved.

    After comparing the solution to a standard solution i found that the Umbraco folder had a web.config that restricted access to the backend.

    Thanks for your help.

    Wow, well found!

    Sometimes these things are hidden in plain sight... that's the last thing I'd have thought of.

    Glad you're back in business.
