On my desktop, I clicked on Reload Skip Cache, and when I inspected the Javascript-produced HTML with Web Developer Tools, I couldn't find any IMG tags for the pieces. I changed graphSuffix to graphicsType in a preview, but it didn't change the result.
Two things that could play a role here:
The Diagram below also uses the wrong key for graphicsDir. So by default it uses /membergraphics/MSinteractive-diagrams/ instead of your rendering script, and there are no .svg files there.
The pieces in the Diagram are drawn as background. To know what is actually used as image URL, I always use the images in the piece table (rightclicking those in FireFox, and select 'inspect' from the context menu that appears).
When I corrected the graphicsDir and graphicsType keys in that comment, the pieces did show up in the table. But still not on the board. Perhaps SVG rendering is not supported for background images, in FireFox?
