Noobie install error: "Warning: Invalid argument supplied for foreach() in ...modules/AOR_Reports/AOR_Report.php on line 85"

I’m getting the following error on install.

It doesnt seem to cause any problems to the running of the application but I’m concerned it could be an issue down the road.
Could someone advise me please how to fix the above.
My thanks in advance.

This is a known issue with the installation and it only a warning, it shouldn’t cause any issues with application
