Comment 7 for bug 151951

I looked into this, and it seems the following is happening:

When you press the button for the configuration screen, a file "jsMath-controls.html" is loaded.
This file exists on the filesystem, however the FileSystemSite product in Silva changes the name of the file
into "jsMath-controls" and then sets the type to be a pagetemplate.
The file also has errors in html, so when executed as a pagetemplate it returns errors.

I don't think we can solve this unless we change something in SilvaJSMath.
In previous versions i was able to suppress the "No jsMath TeX fonts found" menu,
without changing the jsmath javascript code, but as you pointed out, the message is quite useful.

I'm not sure what to do here, either we try to suppress the message, or we try to change FileSystemSite, or we
change JSMath. All tree options are far from optimal.
