I encounter small problem.
I was using my localhost in combination with opus i order to get more productivity.
So i wanted to give and php-script a {filepath} parameter, but one sign " come allway at the end.
Even if i use nofilenamequoting
That does not seem to happen here. Are you sure the problem is with Opus and not the web browser (which may not be expecting those symbols in that part of the URL unescaped, for example)?
Try pasting the same URL, with the actual path and without any quotes, into the Start -> Run dialog to see what happens.
