bugzilla web problems?

When I attempt to enter a new bug against Fedora using Firefox on Fedora 25
at <a href="" title=""></a> and click on Submit, then bugzilla displays
an error page with the message
Access to the file was denied

The file at <a href="" title=""></a> is not readable.

It may have been removed, moved, or file permissions may be preventing access.

This happened twice over a span of about five minutes. Perhaps I'll try again tomorrow.
