Help with mobile internet and wifi?

[Bronte]

I've got a new phone (samsung chat) and am trying to use my home's wifi on it. It connects fine and I can browse some websites, but quite often a 'certificates' screen comes up asking me to 'accept' or 'reject' and a little earth icon with a padlock appears at the top of the screen. But no matter if I click accept or reject, the same thing just pops back up again. HELP PLEASE??

e.g. I go on facebook from the 'communities' link in my menu, news feed comes up fine, as does my profile, but when I go to 'pictures' or try to click on someone's profile it asks 'access the internet?' (which is weird, aren't I already on the internet?) then I click ok and the certificates screen comes up.

Confused :/

It looks like whatever application you are using in phone is not fully allowed to internet access.
You should check out application access to the internet in somewhere in settings menu.
I don't know how to get in there on Samsung Chat.
