When opening a task , created by a Request Data action (edit item) to complete the task I run into an error:

"The control type 'Nintex.Workflow.ServerControls.ApproverSecurityCheck' is not allowed on this page. The type Nintex.Workflow.ServerControls.ApproverSecurityCheck, Nintex.Workflow.ServerControls, Version=1.0.0.0, Culture=neutral, PublicKeyToken=913f6bae0ca5ae12 could not be found or it is not registered as safe"

Other tasks types and Nintex workflow editor give no problem.

What can be the problem?

Background info that might help: Previously I installed trial version Workflow Enterprise and Nintex Forms. Customer bought only Workflow Standard license. I deactivated Forms solutions.

    Hallo Gokan,

    Thanks for the reply. Your diagnose is correct. But I already had activated the web apps, but I guess retracting the NWF enterprise un registered part of the solution

    I got the following solution from nintex support:

    Edit web.confog. Add the following two lines:

    <SafeControl
    Assembly="Nintex.Workflow.ServerControls, Version=1.0.0.0, Culture=neutral,
    PublicKeyToken=913f6bae0ca5ae12"
    Namespace="Nintex.Workflow.ServerControls" TypeName="*"
    Safe="True" />

    <SafeControl
    Assembly="Nintex.Workflow.ServerControls, Version=1.0.0.0,
    Culture=neutral, PublicKeyToken=913f6bae0ca5ae12"
    Namespace="Nintex.Workflow.ServerControls.WebParts"
    TypeName="*" Safe="True" />

    This would need to be added under

    <Sharepoint>

    <SafeControls>

    Followed by IISreset.

    That did the trick.
