Can't edit thread or save.

[angkor408]

For some reason i don't have any problem posting message. If I want to post new message and click on edit or save it doesn't do anything. I saw an exclamation point on the buttom left of my site that say " error on page. When I click on " More detail" this is what I get:

Line: 300
Char: 3
Error: Object Required
Code:0
URL: http://www.khmerclub.com/showthread.php?t=481.

This is happen when I ugrade from 3.5 to the lastest version 3.67.


If I click on the big " Blue box below the save that say" EDIT" than go to "save changes" it work fine.

Any reason why I have to go to this mode?
