Missing or not expected HTTP response headers

Same problem here…

There schould be something more wiht backwpup in the header. Will be some headers removed on your installation ?

I’m sorry, I don’t know what that means. Can you please clarify what you’re asking?

I have not removed any headers.

My backups also work when reverting to the earlier BackWPup version.

I also got the same error? May I know, which version is working? I’ve been trying last 2 version prior to the recent one.

I have change a littel thing on checking in the last version. Now there will be a header x-backwpup... send and checked if that header comes back.

is a reverse proxy active?

Not sure about reverse proxy, but my stack is nginx + hhvm + mariadb + redis cache

It is installed using easyengine script.

Getting the same error and yes, the site is behind a reverse proxy.Reverting to the previous version of BackWPup restores functionality

I’m sorry, I don’t know what this means: “Now there will be a header x-backwpup… send and checked if that header comes back. is a reverse proxy active?”

I tried updating the plugin on a different WordPress website hosted with a different hosting company, and this is the error message I get:

(Note that there was a string of letters & numbers after “set cookie” above, which I deleted in case it is a security risk).

So now I’m seeing the same issue across three websites hosted with two different hosting companies. These are all standard WordPress installs.

Same problem here:

I reverted back to a previous version of backwpup (from backup) and the error went away. This certainly looks like a bug in the 3.2.4 update. If you have not updated yet, don’t.

Interesting – well I only loaded 3.2.4 for the first time on a clients site – used it many times elsewhere – replaced it with 3.2.3 but the problem has NOT gone away!

Same problem here…

Same problem for all my sites and clients sites.
Problem occurred when I updated to the latest version.
