Problem Editting Pre Migration Content

Hello,

I’ve made a site hosted on a test server, it works perfect! Previously it was on my PC without any issue. But when i migrated it to the definitive server i had some troubles editting existing posts or pages or text widgets with html content.

Here is he error I get when I press update to a pre-migration post:

Precondition Failed

The precondition on the request for the URL /intronica/wp-admin/post.php evaluated to false.

Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.

Apache/2.2.22 (Unix) mod_ssl/2.2.22 OpenSSL/0.9.8e-fips-rhel5 mod_bwlimited/1.4 Server at intronica.com Port 80

When I create or edit a new post (post-migration) I have no troubles.

I think it could be because the definitive server may have mod security running, if that’s the problem, please help me to fix it and get it running!

Thanks.
