This one is really strange. I have a development site that was up and running fine for a few months. I made a couple of changes to some templates and .js files today and now when I try to login to Umbraco at /umbraco/login.aspx I get a page not found error.
I've verified in the web config that reserved directory is still:
I've checked the file system to make sure that /umbraco/login.aspx is still there.
The front-end of the site comes up fine.
This is a total head scratcher.
Next I tried installing a backup from the day before I made these changes.
One thing I should also mention is that I added some web methods for a web service in a .cs file in the AppCode folder.
Once I started having this problem I removed.
Also, when I recycle the application pool, then try to load /umbraco/login.aspx, I always get this error once:
Server Error in '/' Application.
Value cannot be null.
Parameter name: virtualPath
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.ArgumentNullException: Value cannot be null.
Parameter name: virtualPath
Source Error:
An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the exception can be identified using the exception stack trace below.
or I just reinstalled the Umbraco instance, attached a backup, and moved copies of all my templates and media into their respective folder - indirectly "solving" the problem.
The other odd-ball thing that happened when I got these kind of errors was that the ~/config/applications.config file got wiped out (as in the file was still there, but it was just a blank document - everything erased inside.)
can't login, /umbraco/login.aspx not found
Umbraco 4.9.1 on WINS 2008 R2

I have no idea where to look or why this happen.

Then if I reload the page, it goes back to a page not found error.
I've also restarted the server and restarted the database server as well. Nothing.
Hi Jacob,
did you find solution for this, I have the same problem?
I'm usually pretty good about leaving myself notes, but on this one I did not. I either deleted the temporary asp.net files under the root directory: http://stackoverflow.com/questions/16137457/asp-net-temporary-files-cleanup
or I just reinstalled the Umbraco instance, attached a backup, and moved copies of all my templates and media into their respective folder - indirectly "solving" the problem.
The other odd-ball thing that happened when I got these kind of errors was that the ~/config/applications.config file got wiped out (as in the file was still there, but it was just a blank document - everything erased inside.)
Sorry I couldn't be more help. Good luck.
is working on a reply...
