cannot verify server identity stuck
I need help. My Mum's Ipad is stuck on this CANNOT VERIFY SERVER IDENTITY screen.
there is three choices
Cancel
Details
Continue
Clicking on cancel does nothing the same menu pops back up straight away.
Clicking Details shows me a my mail server is not trusted. ( it had expired but has since been reactivated) other than this i click accept and it brings me back to the initial menu
Clicking Continue does nothing also just refreshes the original menu.
This has made the IPAD totally unusable as I have no idea how to circumvent this **** menu. At least if I can go into other parts of hte ipad I may be able to change some settings or disable the mail so the ipad can be used but as it stands now its just worthless paper weight.
Urgent advise needed.
