WebReports displays a blank white screen instead of data


When viewing WebReports within WorkStation or Internet Explorer the report data is not shown. All that is seen is a blank screen even though the menu items are still displayed (as shown in Figure 1 below).

When viewing the same WebReport through a different browser, Chrome or Firefox the report displays correctly

The issue has only been seen with Internet Explorer since the other browsers appear to work. Since Building Operation WorkStation uses Internet Explorer as its internal browser, the problem is seen when displaying WebReports within WorkStation.

To confirm that this is the issue you can check the Windows Event Log contents (Application Log Warnings) related to:

<Provider Name="ASP.NET x.x.xxxxxxx.x" />

To correct this issue ensure that the Windows Regional Language, found in the Windows Control Panel matches between the Workstation PC and the Reports Server.
