The following website is blocked on the school network but only for this student's website. Other students have used the same hosting provider and are on the same network with the same code, as far as we can see, and their sites are not blocked.
The blocked page and site URL is below:
http://minimalstocks.atwebpages.com/login.php
See the image for the error description.
Access has been blocked as the threat Mal/HTMLGen-A has been found on this website.
The login script contains very basic PHP code and as mentioned other students have used identical code using the same hosting provider and the code/page works with no errors on the same network.
Any thoughts as to what could be causing this error?
