我正在使用vBulletin 4.1.4版。我想重新设计登录页面（它与当前的vBulletin皮肤分开），我尝试使用这些说明http://www.vbgeeko.com/archives/217，但它显示错误：
Warning: fetch_template() calls should be replaced by the vB_Template class. Template name: navbar in [path]\includes\functions.php on line 4114
( ! ) Parse error: syntax error, unexpected T_STRING in D:\wamp\www\vBulletin Forum v4.1.4\upload\clogin.php(42) : eval()'d code on line 1

那么如何创建vBulletin 4的自定义登录页面？
