XF 1.4 Response not JSON! when editing a template

[polle]

I just update to 1.4.3 I revert the template, I went to page container to add my code, I hit save and I get "Response not JSON!".

Nothing is saved.

If I hit save and close I get a 403 in a blank page.

Of course this did not happened in 1.4.2.

I really need to add my code.

How to fix it ?

Thanks

Does it work if you disable JavaScript in your browser?

If you use Chrome - chrome://settings/content

I get a message at the top that is needed.
I continue and manually find "Page_container", hit save and I get a 403.

So no, its not working either with JavaScript disabled.

Thanks.

Solved, it seems it was a server issue.

Thank you.
