As most of us in SharePoint industry aware, SharePoint March 2013 Update is the new baseline update for SharePoint 2013 farms and all the servers must be upgraded to March 2013 Update before patching to later Service Packs and Cumulative Updates.
Unfortunately, if you are using SharePoint Publishing Features to host articles and web content management features, you will encounter multiple issues and your authors won’t able to update articles in several scenarios. I have came across several issues – e.g. Calling CSOM APIs or referencing Managed Metadata Fields from Page Layouts.
Please review these two articles, understand the logic behind, and plan to patch your SharePoint farm to latest service pack or CU. At the time of writing this article – I was able to fix these issues by upgrading to the August 2013 CU.
- SharePoint March 2013 Public Update, Invalid FormDigest, Client.SVC ProcessQuery 403 Forbidden
- SharePoint 2013 March Update, Invalid FormDigest, Taxonomy Field in Publishing Page Layout, ValidateTerms 500 Error, and “There was an error processing the request” Error
Hope this will avoid several hours of headache for some of you out there.
