I have a problem with my WSA. Occasionally I get blocked images from different websites. For example www.onet.pl, I can see from accesslogs that url's for particular images are blocked because they are uncategorized, here is the log:
Then this is the reason why. As of the accesslog entry, you can see the URl is not categorzied ("nc"), hence the request will be blocked if set to block. An custom category will always overwrite, so this is working as workaround. You may want to consider then to not block non-categorized URL's.
In case it is just about this specifiy URL, you can always as customer open a support case to let the page get categorized if feasable.
