Load Test Report displays <Error Detail disabled>

Hi All,

Observed <Error Detail disabled> message in the Load Test report.
I am sure that i have selected the below options while exporting the Load test results in the "Create Report" window.

Format: "LoadTest Report" option is selected from the drop down list.
Options: "Detailed Error Information" is checked

But still i am getting "<Error Detail disabled>" message in the LoatTest report pdf file.

Any help on this greatly appreciated.

Thanks,
Naveen
