Hello Martin In my case, I found the problem. In the file /include/view.w.php I swaped the readout of the variable $result (line 180): $result = mysqli_query($sql, $db); $result = mysqli_query($db, $sql); Comparing the php files from version 8 to 9 I discovered this change and it obviously was forgotten to be adapted in this file.

Hello Martin I recently installed PHP Address Book (php-addressbook v9.0.0.1) and I found the same problem as you describe. I followed the link to the demo (php-addressbook v8.1.24.1) and there the groups are displayed in the detail view. Did you get any feedback or solution?
