method or function called twice but only with one browser

[eluser]GabrieleMartino[/eluser]
Hello everybody,

I have a function in my method 'enter'

Code:

$this->chats_model->add_message(...);

called twice with Mozilla or 1 with others browser. It should be executed once instead I have two records

in the database. With Chromium and Konqueror works fine.

Thanks for help

I found the solution on another thread,

anyway it was to put the tag

Code:

<meta http-equiv="Content-Type" c charset=utf-8" />

At top of his page.
