dnn中 的captcha验证码控件的使用问题
用户注册时,如果打开此页面超过Expiration设定的时间,图片则生成不成功。默认过期时间为120秒。

原来: <dnn:captchacontrol id="ctlCaptcha" Expiration="2" CaptchaWidth="135px" captchaheight="40" Width="135px" ToolTip="输入字符不分大小写" CSSclass="Normal" ErrorStyle-CssClass="NormalRed" runat="server" />

解决办法:删除Expiration:
                                <dnn:captchacontrol id="ctlCaptcha" CaptchaWidth="135px" captchaheight="40" Width="135px" ToolTip="输入字符不分大小写" cssclass="Normal" ErrorStyle-CssClass="NormalRed" runat="server" />

错误日志如下:
