You may encounter an error similar to the following when attempting to generate Articulate Online reports:
Page Not Available
When a content item has multiple revisions (updates), reports could fail if the amount of data being compiled exceeds SQL limitations. You may be able to avoid this error by changing the date range for the report to a shorter time span, which should require less data. Depending on the number of revisions and when they were made, however, changing the date range may not always work.
To avoid this issue, we recommend keeping the number of content revisions to a minimum, since they can make reports so data intensive.
