Display on iPhone has gone to pot - responsive design

[CallerIDBingo]

I access mumsnet on my iPhone.

Responsive design isn't working - so instead of a thread fitting into the width of the screen, it's showing like the desktop site and it's impossible to read.

Been like it since yesterday, I'm using Safari.

Is there a fix?

Bump! Because I'm in the garden and it's impossible to use MN on my phone!

Did you try going to the v bottom and in tiny letters it says mobile site.

Wips may be onto something there - it sounds like you've accidentally put yourself onto the desktop site.

As Wips said, if you go right down to the bottom of the page, there will be a link which will take you back to the mobile site.
