Trolled with hosting

[stufflol]

Hosting newbie here, uploaded my page and content to my domain monster hosting, and I am now getting the above image when I try to view it... is this someone trolling me? Have I not configured the security correctly or something?

When I open the page on the FTP it works fine...

Any help appreciated

I can't really give out the domain its from work

Is there anything I can do?

I get this

'Not Found

Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.'
