Good morning everyone, I'm trying to export the list of my users but when I try it I get this error message:
0 array_diff_key(): Argument #1 ($array) must be of type array, null given

how can I fix it?
Thanks

Which exact version of AcyMailing are you using?

This kind of error appears in case you are using PHP 8 with older versions of AcyMailing 5

the version is the 5.10.4

What about the PHP on your server?

Also, please update to the latest version, which is 5.10.24

The PHP version is the 8.0.15. What should it be to let Acymailing working fine?
Thanks

As said, update to the latest version which is 5.10.24

The server say that the 5.x.x PHP version is obsolete.

PHP 5.6.x is, but you can use PHP 7.x

But, please, can you just do what I suggested?

Update your AcyMailing to the latest version, which is 5.10.24. I am not talking here about the PHP version, but AcyMailing version

Sorry, you are talking about the Acymailing version...

Exactly

I will right now. thank you

Nothing, I updated it but I get always the same message

Try also to lower your PHP to 7.x
