The security validation for this page has timed out

While working on browser enabled InfoPath forms, I got the following error message:

The security validation for this page has timed out. Click back in your Web browser, refresh the page, and try your operation again.

Troubleshoot issues with Windows SharePoint Services.

Valuable comment from Clayton Cobb: “What you're experiencing is the BROWSER timeout for SharePoint, which of course affects browser forms, but it's not related to InfoPath.  It's a farm setting for all of SharePoint, and it's related to the browser security, not InfoPath forms.  Your users aren't hitting an InfoPath timeout; they are hitting a browser timeout.  The default is 30 minutes, and that's to protect your system from security breaches.  If you want to change it for people to fill out InfoPath forms, then you're going to have to change it for the entire farm, and it will affect all browser sessions unrelated to InfoPath.

My recommendation is to provide a custom save button that allows the user to save progress along the way”

What resolution I have applied:-

1)   Open the SharePoint 2010 central administration

2)   Application Management section

3)   Click on Manage web applications

4)   This will open the Web applications list page.

5)   Select the particular web application

6)   Click on General Settings from the Ribbon.

7)   This will open the Web Applications General Settings dialog box.

8)   From there Web page Security Validations property

9)   Change the Security validations expires which is by default 30 minutes to Never.

The document could not be opened for editing

When opening a document from a SharePoint library on a specific site collection, I am receiving the following error.

 "The document could not be opened for editing. A Microsoft SharePoint Foundation compatible application could not be found to edit the document"

Multiple resolutions:

1)   Make sure you are using IE 32 bit. IE 64 bit is not fully compatible with SharePoint

2)   Go to the document library's settings, advanced settings and check the settings for Opening Documents in the Browser

3)   If using IE 32 bit, check if "SharePoint OpenDocuments Class" is enabled under Tools -> Manage add-ons

4)   Make sure "Open Documents in Client Applications by Default" feature is activated for the site collection

5)   Try changing "Browser File Handling" of the web application to "Permissive"

6)   Try adding the SharePoint site to the Trusted Sites zone of the browser

7)   Check this- http://sharepointknowledgebase.blogspot.com/2013/10/edit-document-requires-windows.html

8)   Make sure the client integration is enabled in central administration

If you have any queries/questions/confusion regarding the above mentioned points then please let me know. I would be more than happy to help you as well as resolves your issues, Thank you.
