Occassionally, when viewing a page in SimpleRisk, you will receive a message like:

DataTables warning: table id=DataTables_Table_0 - Ajax error. For more information about this error, please see http://datatables.net/tn/7

We typically see this in places like the Dynamic Risk Report where we use asynchronous javascript calls (AJAX) to the SimpleRisk web service to retrieve data.  This error message indicates that one of the responses it received back from that services was not a 200 (success) code.  Typically, this is indicative of either the service not being set up properly or an issue with the service retrieving the data from the database.  You should check your database instance to make sure that everything is working properly.

UPDATE 1/24/18: It was determined a bug exists causing DataTables warnings when SimpleRisk is installed to a subfolder of the context root. If you are experiencing this issue the current work around is to leave your SimpleRisk installation in the context root (i.e. "/var/www/simplerisk") or to change your vhosts.conf to reflect the documentroot to be the SimpleRisk directory. We are working to have this bug alleviated in the next release.
