I am facing an abnormal problem in a site. Where when I was trying to login with "Chrome", it is running fine. But when I am trying to login with "Firefox" or "Internet Explorer" it is not allowing me to login.

In Firefox it is showing error as :

Mozilla/5.0 (Windows NT 6.1; rv:5.0) Gecko/20100101 Firefox/5.0

And in Internet Explorer it showing :

Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.1; Trident/4.0; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729; Media Center PC 6.0; AskTbFXTV5/5.8.0.12304)

What may be the possble reasons?

Thanks in advance.....

That's not an error message, but the user agent string of the respective browser. Search your code for something like

echo $_SERVER['HTTP_USER_AGENT'];

That may lead you to the position of where things go wrong.
