After september 2018 Sharepoint update KB4092470 all "Collect Signatures - Sharepoint 2010" workflows do not run or publish any more.
Along with SP update the following have been also applied: KB4457915, KB4457919 (.NET); KB4457140, KB4457135 (Windows 2012 Server), KB4457426 (IE10)
Error from logs:
Type System.CodeDom.CodeBinaryOperatorExpression is not marked as authorized in the application configuration file
I added in web.config from C:\Program Files\Common Files\microsoft shared\Web Server Extensions\15\CONFIG folder and also in web.config file from the web app dir in C:\inetpub\wwwroot\wss\VirtualDirectories\8190 the following line:
<authorizedType Assembly="System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" Namespace="System.CodeDom" TypeName="CodeBinaryOperatorExpression"
Authorized="True"/>
but with no effect.
Windows Server 2012, Sharepoint 2013 SP1
All Sharepoint 2010 Worflows (Approval, Collect Feedback, Collect Signatures) have the same issue.
Need some help please.
