https fail on some pages ...

[DGRossetti]

certainly on some threads:

Just thought I'd flag it up. Your main page is OK, but there's something evil somewhere

Hi there OP,

Thanks for getting in touch about this. Have you noticed any particular trends with this? For example, is it only happening on certain talk topics?

Well it's not happening on this thread

Nor this one:

www.mumsnet.com/Talk/am_i_being_unreasonable/a3478239-to-object-to-50-school-trip?msgid=84116369#84116369

However, it is happening here:

www.mumsnet.com/Talk/_chat/a3476166-comprehensive-list-of-americanisms?msgid=84116050#84116050

At a guess, one of your advertisers has embedded something non https into their pages (probably without realising it).

Hi again OP,

Thanks for getting back to us. This is most likely something to do with an ad on the page. We're certain that the site is definitely secure, so no need to worry.
