ScriptResource & WebResource Errors

Question

Here is a picture of the errors:

Here is a copy of my web.config:

<?xml version="1.0"?>

<configuration>
  <connectionStrings>
    <add name="BaseConnectionString" connectionString="Data Source=BRYAN-PC;Initial Catalog=Base;Integrated Security=True"
      providerName="System.Data.SqlClient" />
  </connectionStrings>
  <system.web>
    <compilation debug="true" targetFramework="4.0"/>

    <sessionState
              mode="InProc"
              stateConnectionString="tcpip=127.0.0.1:42424"
              sqlConnectionString="Data Source=BRYAN-PC;Initial Catalog=Base;Integrated Security=True"
              cookieless="false"
              timeout="500000"
      />
    <httpRuntime requestValidationMode="2.0" />
    <!-- Prevent excess code to clutter source -->
    <pages buffer="true" validateRequest="true" enableViewState="true"/>
 </system.web>

</configuration>

I am curious as to why these errors are happening. The only ajax I have going on is the jsTree pluggin which originally wasn't showing these errors. I set up the jsTree plugin to use [System.Web.Services.WebMethod] to talk to the code behind.

Can anyone shed some light on how to fix these errors? The code or it's functionality isn't broken but these errors clearly show that I am missing something.

IF anyone requires additional information, please let me know. Thanks!

EDIT: I forgot to mention that it didn't matter what page I was on. The errors shows up all the time.

EDIT2: I am not even using any AJAX Toolkit things at all so I removed it and the ScriptResource issues went away but not my WebResource Issues.
