My Site is not opening in IE. I know about CSS incompatibilities this is why I added the following code to redirect to a static page if UserAgent belongs to Internet Explorer. The code that detects IE and redirects is given below:

Site link is:

http://adnansiddiqi.com/main.html

http://pastebin.com/MCRbsrmi

The header file is included on top of the main.php

Please guide!

    Now that you’ve got the site working properly, we finally have an error message:

    Warning: Cannot modify header information – headers already sent by (output started at /home/adnansid/public_html/main.php:10) in /home/adnansid/public_html/header.php on line 15

    See item 6 from the list below. Don’t call header() after you’ve already sent output. You must call it before any and all output.

    Here are a series of things you need to fix/address/attempt:

    1. Two undefined variables, isMobileSafari, and isOldMobileSafari.
    2. Your <title> needs to be within your <head>.
    3. No doctype was provided.
    4. You’re not outputting anything after the opening <body> tag.
    5. Check to make sure you have short-tags enabled (try using the longform <?php ... ?>)
    6. Don’t call header() after you’ve already output content.
    7. Check your log files for any obvious messages.

    I tried accessing the same page in Chrome, thinking maybe you had broken your user-agent sniffing code, but I found that within Chrome as well nothing is output after the opening <body> tag.

    I would try to diagnose the reason why your body isn’t being output, but you’ve not provided enough code for us to do that. Please provide us a bit more to further assist you.

    The quick solution is to avoid user-agent sniffing code, and instead detect features.
