NI web server can't show Tag History. The request for tag history failed with error code 404

[Labmecepel]

Hi, 
Im developing a web application with NI web server, and i ve come across with an error.

I am sucessfuly creating and updating tag values, moreover i am able to see their values, however i cant read their history

string : "history" button doesnt highlight, therefore i cant click it.

doubles and  i32: "history" button highlights, and when i click in the "history" button i get the 404 error written in the title.

Furthermore, i tried to debug not only in labview but also in g web and both of them had the same error code : -251047.

Labview error:

Gweb error:

I dont know if this error is causing the history error in the NI web server, nonetheless i cant read their history in both softwares.

The same thing is happening with alarms(404 error), but i am not using them at the moment

Tag history and Alarms are not part of the features included with G Web Development Software. Those are services that are included with SystemLink Server. The How to Build a Web UI for Your LabVIEW-Based Test System @4:32 gives a discussion of how the services included with G Web Development Software compare to those of SystemLink Server.
