Threads not loading and loads of computer jargon

[DeltaFlyer]

A few times in the last few weeks, including 3 this evening, I've clicked on a thread and it's loaded a few posts (usually just the OP) and all that follows is load of computer jargon.
Also happens on the page where all threads are listed.
I refresh the page and it does back to normal.
Using a Samsung galaxy a3 on the internet to access mumsnet.

@MNHQ?

Hi DeltaFlyer,

We're really sorry to hear this - would you be able to tell us whether you're using the app or the desktop site? If you're using the main website then do let us know which browser you're using.

We'll make sure someone takes a look at this but the more information you can give us the better.

It's the website.
Samsung internet browser on Samsung galaxy a3 if that helps

I get this, too, on a PC using Firefox (always the latest version).
