Having trouble for a few hours getting MN Talk on Chrome, I can get the homepage and some other "pages" (eg pregnancy info - though a bit slow to load), but any links to Talk threads or topics get "This page isn't working. www.mumsnet.com is currently unable to handle this request. HTTP ERROR 500".
It seems ok on my phone and (based on a quick look) on Edge though. It might be a problem my end, but letting you know in case! (PS off to bed soon so may not reply to any Q's till tomorrow).
