Summary

Audit Trail Reporting may be unable to generate charts when hosted on IIS 7.

Cause

Changes in the Web.config format between IIS 6 and IIS 7 require an additional line to the Audit Trail Reporting Web.config file.

Resolution 1

This issue is resolved in Laserfiche Audit Trail 8.1 and later. Please upgrade to the latest version of Laserfiche Audit Trail.

Resolution 2

Manually modify the Web.config file.

To modify the Audit Trail Reporting Web.config file

1. Using a text editor, open the Web.config located in the "WebAuditReporter" subfolder of your Audit Trail installation location. By default, the path is "C:\Program Files\Laserfiche\Audit Trail 8\ WebAuditReporter."
2. Locate the <handlers> section.
3. Add the following line before the </handlers> tag:

   <add name="ChartImages" verb="GET" path="cachedimageservice.axd" type="ComponentArt.Charting.CachedImageService,ComponentArt.Charting.WebChart" />

4. Save your changes and close the file.
