Question Some posts wont submit after editing?

I'm using Joomla 2.5.20 and Kuena 3.0.8 and I cannot edit SOME posts in the forum. I cant tell for sure why they do not edit.

What happens:
I open the post, I click edit, the editor opens.
I make a change and click submit. Then nothing happens. The page does not reload, or change at all. Its as if the submit button didnt work at all.

I can click preview and see my change is present, but submit still does nothing.

Note: This doesnt happen on all posts, some of them I can edit normally.

Any ideas why this happens?

1) Update Joomla
2) If have seen this issue this week, So there is a plugin, that's broken.

So disable all None default joomla and kunena. Then enable your plugins one by one

I have no kunena plugins enabled. Also, why would only certain posts have this issue? The majority of them I can edit properly, which suggests the version of Joomla itself shouldnt be an issue either. I also tested this in both IE and Chrome and with two different admin level usernames and both did this.

Your forum may not operate properly unless you enable a couple of Kunena plugins. It may help if you could provide us with a copy of your configuration report (as recommended at the top of this page) so that we can see how your website is set up. The better—and faster—the information you can provide us, the quicker and better we can help you resolve your problems. Thanks.

And, yes, 810 has given you a good tip: J! 2.5.20 is very old, outdated and that version is not recommended. It would be a good idea to upgrade Joomla to (at least) J! 2.5.28.
