hmm, that has nothing to do with 4.2 but that the pagenumber is invalid if pagenumber is 0 this error will occur

open archive_functions.php

find:

PHP Code:

    $vars = array(
        'id' => $infos[0],
        'pagenumber' => $infos[1]
    ); 


and change into:

PHP Code:

    $vars = array(
        'id' => $infos[0],
        'pagenumber' => max($infos[1], 1)
    ); 


that should help
