In order to accept POST request originating from this domain, the admin must add this
 

I have installed the vb4 on local machine to test before I set on the server. Forum runs fine, but when I try to save anything from the admin CP I get this error:

In order to accept POST request originating from this domain, the admin must add this domain to the whitelist.

I tried to add the url to the forum on General Settings, but I cant even save it rather getting the same error.

Anybody could suggest a solution?

must have a configuration problim in config.php
your running apache and all that on the local machine? PHP 5 or above

I am on PHP 5.2.6

Only thing I edited on the config file is db info and the admin email, thats all.

Nobody?
