And again. One post and 400ed.

This is not how other sites with lots of advertisers work. Because they actually work.

This is unsustainable. Sort it out.

And that last for me to post once and then I got error messages again.

It basically unusable on my phone. And yes I'm on chrome.

On Android. Was fine yesterday on my laptop and phone. Now having the errors of doom again. Deleted cache once. No joy. Deleted a second time and now working.

This is not a me problem. It's a lack of testing problem.

It is All a very odd response

IDontHateRainbows · 13/05/2026 09:04

Mumsnet sure are doing a great job of dissuading people to use the site, it's so annoying having to constantly go in and out of incognito mode and if I stay in incognito mode I have to re log in to all my other sites. @BeckyAMumsnet is anything actually being done about this or are you just going to rinse-repeat on the clear cache advice?

Sherunswithwolves · 13/05/2026 08:53

It's been happening to me since yesterday / perhaps Monday night on Android and Chrome. I can browse in Incognito mode but that's it.

ShowOfHands · 13/05/2026 07:52

This has just started happening for me. Clearing the cache works for about 5 minutes.

On Android using Chrome.

Weird.i just got the error message (sorry don't know if 400 or 404) .
Used the method in my screenshot above and it worked.

This worked for me too, despite having cleared my cache previously

Happytaytos · 13/05/2026 06:59

Back again this morning.

MrsClatterbuck · 12/05/2026 22:07

Getting 400 bad request when trying to open AIBU or any other. On a tablet Honour but works OK on my Samsung phone.

Happytaytos · 12/05/2026 21:48

Android chrome here

Deleting the cache works for a while, then I get the 400 error again.

Tontostitis · 12/05/2026 21:16

I've been getting this for the last day on Android

Happytaytos · 12/05/2026 21:02

I keep getting verified by cloud flare too, wonder if the 2 are linked.

Happytaytos · 12/05/2026 21:00

Been fine all day after clearing my cache yesterday, now just got a 400 error. Back on incognito but tempted to go. It's definitely not a me error at this point. Needing to delete everything all the time isn't normal.

RNApolymerase · 12/05/2026 18:08

This happened on my laptop last week but today has also started on my phone, four times so far. Clearing last 15 mins of data solves it for a while but a few hours later it happens again

Linksrechtsgeradeaus · 12/05/2026 16:40

I'm not on Chrome but have just cleared everything yet again and it's worked. Fingers crossed it continues to work! (It only lasted a few days last time)

Chrome on android

Three dots on search bar
i (info button)
Cookies and site data - clear (just for mumsnet)

Log back in

Let's see if that works for more than a day!

Various methods suggested if you Google clearing cache for one site.

Still experiencing this on the Samsung browser - clearing cache hasn't worked unfortunately.

LostTheWill29 · 12/05/2026 13:17

I've had no problems on mumsnet until this morning, repeatedly getting the 400 error code. Since it started this morning, it makes no sense that the problem stems from something that happened last week/before?

Unfortunately can't find a way to clear the cache only for Mumsnet on chrome and not willing to log out of 400 odd sites to use just one, so looks like I'll be visiting Mumsnet less on incognito!

Hi all. We would really appreciate the chance to speak directly with a few users who are experiencing the problem again after clearing their cache, so we can better understand what’s happening.

If you’re willing to jump on a short call with us, please let us know on this thread or contact MNHQ directly at [email protected].

Thank you, as always.

BillieWiper · 12/05/2026 11:59

It works if you go incognito.

WeMeetInFairIthilien · 12/05/2026 11:37

Seeline · 12/05/2026 09:25

And if MN have fixed it, why does the problem reoccur after people have cleared their cache multiple times?

Yep, same here. Repeatedly cleared. Works for 1 load of the page. 400 error if refreshed or try to load a other page.
