Does "Very frequently" mean every report. If not, how often?
Without knowing what your timeframe is, or any other parameters you may be using, lets see what happens when you run the report from the comand line
First
omnirpt -report list_sessions -timeframe 24 24 -tab -log C:\temp\report.txt
YOu can send the 'log' file to any location that you want,with any filename you want. Then
omnirpt -report list_sessions -timeframe 24 24 -html -log C:\temp\report.htm
I am not so much interested in the content of the report, rather, if the report gives you the strange-looking output
Then, lets send the two reports to e-mail
omnirpt -report list_sessions -timeframe 24 24 -tab -smtp [your e-mail address] Do not include the [ ] characters
omnirpt -report list_sessions -timeframe 24 24 -html -smtp [your e-mail address]
