Strange issue on a production (godaddy)

fireball

Hi again, and sorry for my confusing question.
I have a strange issue when submiting a from (saving) in fuel admin.
When I press "save" the browser refresh page (like normal submit) but the green line with message "data has been save" didn't appear and record not save... When try catch whats happen I saw in console that one of the requests (/fuel/classy/venues/edit/1046 in my case) return "406 Not Acceptable". Some records are saved normal with the request return "302 Moved Temporarily".

When I try to save normal fuel cms page (not one of my modules like the case above) the same request (fuel/pages/edit/1) return "302 Moved Temporarily" and page save normally.

On my local computer the above requests return "302 Found" and everything works fine... I don't know form where to start...

Thanks for your help.

That is a strange error. I Googled around and found a few things:

Is there anything in the content that you are submitting that may be cause the error on the server?

Yes... The problem is in the content that I submit.
I have serialized fields for social links (facebook, twitter,googleplus).
When fields contain "http://" or "https://" the ajax request return "406".
This is only on godaddy server. On my local machine is ok.

I'll looking for solution, but if you have suggestion how to clean or escape data before submit will be grateful.

Is the serialization JSON or PHP serialization on the field? Default is JSON. I've read that it may be an issue with mod_security on the server. Maybe one of the options found here:
