iwms4.6 sql2005版本，报错贴！

已经升级成功，如果有错误会贴在这里，希望对木鸟有帮助！

1、后台登陆首页右侧：http://www1.51gt.com/news/admin_main.aspx 有报错；

2、编辑外部连接贴里有相同的报错，如下：

Server Error in '/' Application.

---

Specified cast is not valid.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.InvalidCastException: Specified cast is not valid.

Source Error:

2、

有人知道是什么问题不,希望木鸟能帮助解决这个问题,因为我发的所有连接贴前台点击时也报一样的错误,

有人知道吗,这个问题怎么解决呀

我等不及了,直接连接到SQL2005数据库上看了一下,发现外部连接贴没有点击数,我分别将日周月点击数设为0,情况恢复!

请木鸟解释怎么办,以后不能发外部连接贴了吗

后台编辑会员时出现:

Server Error in '/' Application.

这个贴子跟到现在怎么没有人回呀,现在这个问题是什么呀

我已经知道错误了,改一下默认值就行了

sql里当然运行正常,然后才去还原的,

iwms-news表中的dayhist;weekhits;remarknum,的默认值都变成null了,改成0就行了;

iwms-member表中的addnum的情况也是一样.

现在问题虽然解决了,但是登陆首页后的第一个默认页面还是有错误,上面已经说过了;

还有就是这种设默认为0的字段还有很多吧,我怎么一一加呢?

紧急求助,在进入后台点内容管理的时候出现：

Specified cast is not valid.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.InvalidCastException: Specified cast is not valid.
