A number of my web sites have been hacked - all seems OK until you add a new page, then you get a hack screen.
Also, any link to a non existent page brings up the hack screen.
There was a file inserted, g.php, which I deleted but the hack remains.
To see what I mean, look at http://www.adriandoyle.co.uk/foo
I have looked through all the wordpress directories and can't find any dodgy files.
Has anyone come across this?
