I've recently included an App_GlobalResources folder into my EPiServer project in order to store some .resx files.

Since adding this folder the admin panel for EPiServer is reporting that:

Parser Error Message: The resource object with key 'login.loginfailed' was not found.

Source Error:

Line 19: 
Line 20:     <div class="loginBox">
Line 21:         <EPiServerUI:Login ID="LoginControl" runat="server" 
FailureText="<%$ Resources: EPiServer, login.loginfailed %>">
Line 22:             <LayoutTemplate>
Line 23:                 <h2><asp:Literal runat="server" ID="FailureText" />
</h2>

Line 21 being highlighted red.

Has anyone experienced this before and know a solution to the problem?

Thanks for any help.
