The URL ‘[url]‘ is invalid. It may refer to a nonexistent file or folder, or refer to a valid file or folder that is not in the current Web in SharePoint

My Work Env:

 I got the error "The URL ‘[url]‘ is invalid. It may refer to a nonexistent file or folder, or refer to a valid file or folder that is not in the current Web"  in SharePoint 2010. The site was working fine, but after few days the SharePoint site got the error.

    In my scenario, the lookup filed does not give this error, because i don't use any lookup field in SP env.

  Root Cause:
   My SharePoint site's DB machine has 0bytes free memory.

Solution:
   I freed some space, then site works as normal.

The server encountered an error processing the request. See server logs for more details in (.svc) WCF Service

My Work env:

When I tried to access the .svc file hosted in IIS, I got the below mentioned error

The server encountered an error processing the request. See server logs for more details.

I didn't get any other clue about this error.

Solution:

I added the line in .svc.cs,

config.UseVerboseErrors = true; in InitializeService() function.

Now I got a much clearer error message on the client side.

Change outgoing Email settings in SharePoint 2013

I have configured Outgoing Email settings in SharePoint 2013. But the FROM email id in the mail shows another Email ID, what actually I have configured in Outgoing Email settings in SharePoint Central Admin.

Root Cause :

    The web application which triggers the mail has different email ID what we configured in the SP Central Admin.

PowerShell cmd to check OutboundMailSenderAddress,

 (Get-SPWebApplication http://SPWebApp).OutboundMailSenderAddress

Check for both, web app and Central Admin URL.

Solution:

I have updated the OutboundMailSenderAddress mail address using SP Management Shell,

$webApp = Get-SPWebApplication "http://SPWebApp"

$webApp.OutBoundMailReplyToAddress = "no-reply@suglog4.net"

$webApp.OutboundMailSenderAddress = "sharepoint2013@suglog4.net"

$webApp.IncomingEmailServerAddress = "suglog4Mail"

$webApp.Update()

Note : If you have more than one WFE and APP server run the above script line for all the servers and check whether the OutboundMailSenderAddress user has updated.

Now check the both the SP Central Admin and  Web App OutboundMailSenderAddress user's are same.

PowerShell cmd to check,

 (Get-SPWebApplication http://SPWebApp).OutboundMailSenderAddress

The imported project "Microsoft.Silverlight.CSharp.targets" was not found. Confirm that the path in the declaration is correct, and that the file exists on disk.

Silverlight 4.0 Projects not open in the Silverlight 5.0 installed machine and shows the below error

Error :

The imported project "C:\Program Files (x86)\MSBuild\Microsoft\Silverlight\v4.0\Microsoft.Silverlight.CSharp.targets" was not found. Confirm that the path in the <Import> declaration is correct, and that the file exists on disk.

Solution:

In Silverlight V4.0 path has only  Microsoft.Silverlight.CSharp.targets file in the path, 

C:\Program Files (x86)\MSBuild\Microsoft\Silverlight\v4.0

but in Silverlight V5.0 has (C:\Program Files (x86)\MSBuild\Microsoft\Silverlight\v5.0) below files,

1. Microsoft.Ria.Client.targets

2. Microsoft.Silverlight.Build.Tasks.dll

3. Microsoft.Silverlight.Common.targets

4. Microsoft.Silverlight.CSharp.targets

5. Microsoft.Silverlight.VisualBasic.targets

6. XamlServices.dll

7. zlib114.dll

I copied all the Missing files except  Microsoft.Silverlight.CSharp.targets  and pasted in v4.0 path. Now projects loads without an issue.
