Symptom

Add the List Filter Plus web part to a web part page.  The page will display the error and stack trace in the summary section.

Resolution

 List Filter Plus uses AJAX 3.5.0.0.  You should check that it is installed and referenced properly in the web.config or your web application.  If it is not referenced properly or is refercing an older version, here is the steps to referece it manually:

1.    In  the web.config, check which version of AJAX you have in line:

<sectionGroup name="system.web.extensions" type="System.Web.Configuration.SystemWebExtensionsSectionGroup, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35">

If it is not 3.5.0.0, they need to change the old version number to new one in all the web.config.  Afterwards save your file.

 

2.       If the AJAX version is reference to 3.5.0.0, you should install the latest List Filter Plus version on our website and check in your web.config if you have the double tags which started with <add name="ScriptModule".

If you have it, you should remove the line below:

<add name="ScriptModule" preCondition="managedHandler" type="System.Web.Handlers.ScriptModule, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" />.  Afterwards save your file.
