After a painful upgrade from version 2.3.1.9 to 2.3.5.4 everything is finally working, however, it is not possible to edit or add blog articles.  It IS possible to edit page layout, but not the contents.  Each time we try to edit an article the following error is displayed in the edit section: HTTP Error 404 - File or Directory not found.  I have checked and all the files appear to be there and security is set correctly.  I need to get this fixed fairly urgently.  Can anyone help?  Thanks in advance.

Platform: OS Windows 2003 Server SP2

Client : Windows XP SP3 and Vista SP1 with IE8/9

Database: Microsoft SQL Server 2005 SP3

There are couple of other things broken, which may be related and yield clues to what is wrong:  the search and clear log functions do not work.  Both result in the "We're sorry but a server error has occurred while trying to process your request ...etc" message.

The url of the file varies, as this occurs for every attempt to use the edit link on every page. The new web.config file is in use and Windows is fully up to date.

Mojoportal System Log only shows an older error:

I am unable to clear the log (message: We're sorry but a server error has occurred while trying to process your request ..etc).  I tried rerunning the application after recycling IIS, the web app, giving the Everyone group Full Control on the Data folder (as a test) and still get the same result.  The web server event viewer Application Log does not log any related errors.

Joe,

I have tried numerous permissions settings, but these do not appear to affect the problem.  When turning off custom errors, I did come up with some potentially useful information:

When trying to clear the Mojoportal system log I get:

+++++++++++++++++++++++++++++++++++++

Server Error in '/' Application.

A potentially dangerous Request.Form value was detected from the client (ctl00$mainContent$txtLog="...erEditor="

Description: Request Validation has detected a potentially dangerous client input value, and processing of the request has been aborted. This value may indicate an attempt to compromise the security of your application, such as a cross-site scripting attack. To allow pages to override application request validation settings, set the requestValidationMode attribute in the httpRuntime configuration section to requestValidationMode="2.0". Example: . After setting this value, you can then disable request validation by setting validateRequest="false" in the Page directive or in the configuration section. However, it is strongly recommended that your application explicitly check all inputs in this case. For more information, see http://go.microsoft.com/fwlink/?LinkId=153133.

After about 3-4 days I finally got things working.  I resolved the problem by manually copying over all the wwwroot files and folders into the appropriate folders and subfolders in the website directory.  Things magically started working after that.  I suspect that the first time I ran setup, the permissions on the Data folder (and possibly others) were too restrictive.  The readme.txt instructions state that to make sure that the site is completely writable by the web process.  This assumes that you know what the web process is and simply having domain admin access is not enough.  At this point I am still not sure what the 'web process' is.  Is it the ASP.NET account or the IUSR_Servername or the NETWORK SERVICE or maybe the IIS_WPG account?

The issue could have been avoided with clearer instructions.  Nonetheless, thanks for your assistance.
