[Support request] Firefox 400 error

[Rob]

Hi,

I have a couple of websites that display fine with Chrome or IE. But, they return 400 errors with Firefox on my computer and others. This is sort of a new problem – I noticed it a few months ago.

Here is one example:

Any thoughts on how to fix this traffic-crushing problem?

Thanks

Hi there,

can you visit that page on firefox if you’re logged in to the site?

Hi David,

Thanks for the reply.

No, I can’t. Firefox just displays an error page. I tried to play with different url adjustments like removing https, going to the home page, and what not.

All error messages. Other people have reported the same problem so I guess it is not a cookie problem.

Some time ago I switched the WP site to https – could that have caused a problem I wonder.

Cheers,

rob

So bad with login – one issue is related to Ajax scripts being restricted to logged in users. So we can dismiss that.

Cookies – well they can get cached by your server cache so have your tried flushing that?

Thanks

I’ll try it.

You’re welcome
