site hackers?

When I access this site on a hand held device (ancient Apple iPad) I cannot log in because a pop up obscures the login box. This started last night. I got round this by going into the mobile mode as this is not affected; I logged in that way. I cannot get rid of the pop up even by choosing 'block'.

Is anyone else experiencing anything odd on this site?

i dont see the popup only after i login does an orange popup box appear

? could it be adverts that your seeing as i understand site does have them but pc does block them

Yes, I am seeing adverts, they were always there but now it is different;

they are obscuring the actual login boxes (username box and password box) and I cannot get rid of the advert that is superimposed over these. This stops me logging in on my handheld device, unless I go into mobile device mode to login. In that mode, I cannot perform moderation duties and I then need to go back into web version to do that.

This problem is new, it had never happened before 2 nights ago; that is what made me think that something had changed.

........update: it spontaneously resolved.
