I just installed BreezingForms and was trying to upload a demo form through the BreezingForms, Configuration => Package Installer, Uploading a xml
I get a "The webmaster has forbidden your access to this site"
My IP is in the Whitelist so not sure why I get this or how to get around it.
I looked at another ticket for Breezing forms which said something about adding an exception but not sure how that is done or if that is really the problem.
The "Upload scanner" doesn't allow uploading of xml files to prevent certain attacks. To disable this feature just go to Waf Configuration -> Upload scanner and delete "xml" from "Extensions blacklist". This should solve your issue.
