Dear All, 
I have uploaded the 5.4.2 community edition and get the following error. I have set the

customErrors mode="Off"

and it still gives exactly the same message. 
Please can someone  advise me what I need to do to get it to work. 

thx 
Rob

Server Error in '/' Application.

---

Runtime 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>

Yes, its quite frustrating...I have read everything I can and tried all the suggestions I have found but cannot resolve it...however I am sure someone can help and I will let you know when they do.

Hi Seb, Yes I did. I have developed .net since beta asp.net in 2000 and often see similar but its normally a server config issue. The server has the latest asp.net 3.5 sp1 and everything is sweet for my others sites. I cannot figure it out... thx rob
