DSpace 6.3 XMLUI glyphicons

[Andy]

Hello;  

We have an instance of DSpace 6.3 XMLUI.  Everything was working fine but, this week, glyphicons-home is displaying as a broken image on all browsers.  When I switch to the JSP view, the glyphicons are fine.  Any ideas?  Attached is the list of files.  I tried installing an updated SVG file but, that didn't work.  Thank you.  Kate
