Cause 1
This was probably an upgraded system where the diagram link was referencing an existing resx file that in the current version has been renamed or does not exist anymore.
The following error is seen when opening a Diagram
No errors were logged in system log and Application module diagnostic event log. But the windows application event log (Start Menu -> Event Viewer -> Windows Logs -> Applications) captured "Error Caught in Application_Error eventError in: https://*ServerName*/ion/Historical/DisplayLogs.aspx?queryId=0a92b9b3-4797-4e92-8da1-4d43988b8615&dgm=x-pml:/diagrams/ud/default/8000_FAC-PQ-61850-4WYE_V1.0.1/8000_FAC-PQ-61850-4WYE_V1.0.1-logs.dgm&node=ST_IVE.PM8240&logServerName=QUERYSERVER.ATAL&logServerHandle=327952&isEventLog=Error Message:Could not find file 'C:\Program Files (x86)\Schneider Electric\Power Monitoring Expert\system\etc\IonNames.en-US.resx'."
Note: It can be another IonName.[Language].resx file as well.
Cause 2
This issue happens when the device icons are pasted in custom diagrams and query server is not properly set in the custom vista diagram pages. When check the url when a meter template is opened you can see the query server name weater it is properly passe or not -

in this case the URL is pointing to wrong query server.

Resolution 1
- Navigate to C:\Program Files (x86)\Schneider Electric\Power Monitoring Expert\system\etc
- Search for IONNames.[LANGUAGE_DESIRED].resx
- Make a copy of it within the folder (Note: Always keep the original in the folder)
- Rename the copy to match the file name that the error is claiming that could not be found
- Perform an IIS reset and refresh the Web Page
Resolution 2
- Open the network diagram in Vista
- Right click on the page and select Properties > Query Server
- Select 'Custom Query Server' > click on the "Edit Link" button > select the local PME query server.
- Restart 'ION Application Modules Core Services Host' service and refresh the browser
