OK this problem is still persisting in v7.4 latest beta and each time it crashes I have to force quit RapidWeaver to escape. Here are my FTP settings...
Mathew, the blue 'i' button Simon was referring to is in the Publishing Panel when there is an error, clicking on this 'i' button reveals the source of the error...
You can see it says "Access denied to remote resource" but I know I have access to my server as I'm able to login through my FTP apps.
Going back to v7.3.3 seems to fix the error and I'll have to do that if I want to publish directly from RapidWeaver otherwise I can export and upload manually.
Simon, what do you think the problem could be?
The only frustration I have with this is that RapidWeaver doesn't allow me to escape from the error upload panel without force quitting, hopefully you'll be able to make the "Cancel Publishing" button active so that if this problem occurs again I can return back to my project file without worry.
