Is there a fix for the CSRF "The action you have requested is not allowed" issue?

[eluser]esset[/eluser]
As you can imagine I have the infamous CSRF "The action you have requested is not allowed" issue. I'm running CI 2.0+.

The issue I'm having is that my code is working using my iPad, but if my friend is using his iPad he gets the error. This behaviour is just super strange.

I've read through 10+ topics and pretty much everyone says just to turn CSRF OFF, I don't really see this as being the solution to the problem. I mean I want CSRF protection to the turned ON, that's the whole point... no?

So has anyone had any look altering the code to fix this issue?

Thank you in advance
