As I said, the current max file size if 1 MB, and those files are well below that. Furthermore, no error was given.

To fix the editpost.php database error:
Open editpost.php:
Find:

PHP Code:

    $attachmentinfo=$DB_site->query("SELECT filename,attachmentid FROM attachment WHERE $qry"); 


Add Above:

PHP Code:

    $att = explode(",",$postinfo[attachmentid]);
    foreach($att as $value) {
       if(isset($qry)) {
        $qry .= " OR attachmentid='$value'";
       } else {
        $qry = "attachmentid='$value'";
       }
    }
