i have a password issue and can't get my gmails on my IOS7 devices any more

Hi, there,

Well, i have a problem with my devices, iphone and ipad2, both ios 7, and the issue is that i renewed my google account password and updated it on my devices but i cannot get my gmail emails any more and i get a Cannot Get Mail message and i'm asked to go back to settings on my device and put in my details again, which i have already done ten and more times, and still, to no use.

I even thought maybe i am not typing the right password, so i checked it again on my laptop computer and all was fine there.

Well, i hope there is a kind of explanation to this.

Thanks a lot,

Totoo
