Wordpress Site Downloads Instead of Opening Page

I’m sorry for the delay, I just got a reply from iFastNet about this. The file downloading issue should be solved now. The blocking issues might not be solved for you though. The underlying system detects certain unusual traffic patterns and then blocks the visitor. The method itself is sound (I’ve seen other systems have similar abuse detection), but might trigger false positives, especially if there is broken code in your website generating excessive error traffic.
