The following code change works for me, it might be due to incompatibility with latest version of php

Change the following code in the myAlbum-P index.php

while( $fetched_result_array = $xoopsDB->fetchArray( $prs ) ) {
$xoopsTpl->append_by_ref( 'photos' , myalbum_get_array_for_photo_assign( $fetched_result_array , true ) ) ;
}

to

while( $fetched_result_array = $xoopsDB->fetchArray( $prs ) ) {
$photo_assign_array = myalbum_get_array_for_photo_assign( $fetched_result_array , true );
$xoopsTpl->append_by_ref( 'photos' , $photo_assign_array ) ;
}
