Before i migrate to version 4 i would like to export all my books from 3.1.5 but this is not possible.

I get this error after pressing the export-key

0 Call to undefined function each()

Hi Bebrona,
the "each" function is not longer available in PHP 8
You have to set PHP 7.4 then try to export again.
Otherwise you can make the backup directly using mysql (eg: phpmyadmin)

Thanks for the answer. I managed to export the file.

But when i try to IMPORT it in version 4.0 I get this error

1064 You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '<br /> <b>Deprecated</b>: The each() function is deprecated. This message will ' at line 1

The export file from abook 3.x is not compatible to Abook 4.x.
To upgrade your website you have to upgrade joomla to 4.x then upgrade Abook installing the 4.x version.

So if i understood this correctly i first have to install Abook 3.x on Joomla 4.x import the files and than upgrade Abook to 4.x?

No, it is not correct.
If you have a joomla 3 website and you want upgrade it to joomla 4 you have to upgrade joomla then upgrade Abook.
The export is not necessary.
