行 36：                                                                                                         <tr>
行 37：                                                                                                                 <td width="30%">论坛的名称:</td>
行 38：                                                                                                                 <td><cc1:textbox id="forumtitle" runat="server" CanBeNull="可为空" RequiredFieldType="暂无校验" width="200"></cc1:textbox></td>

行 40：                                                                                                         <tr>http://localhost/qichi3/bbs/setup/index.aspx正常出现这个，下一步也正常（就是环境检测），再一下步就出现这个错误！
出现错误的是这行：                                                                          <td><cc1:textbox id="forumtitle" runat="server" CanBeNull="可为空" RequiredFieldType="暂无校验" width="200"></cc1:textbox></td>
