Strict Standards: require_once() [function.require-once]: It is not safe to rely on the system's timezone settings. Please use the date.timezone setting, the TZ environment variable or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected 'Asia/Calcutta' for 'IST/5.0/no DST' instead in /home/wwwheyrt/public_html/Sources/Subs-adkfunction.php on line 1
Parse error: syntax error, unexpected T_IF in /home/wwwheyrt/public_html/Sources/Subs-adkfunction.php on line 1
In your php.ini file, add the line
date.timezone = 'Asia/Calcutta'
(or whatever is appropriate for you, see -- http://us3.php.net/manual/en/timezones.php).
List the first 10 lines of your Sources/Subs-adkfunction.php file here. The message is telling you that there is an unexpected "if" statement at the very beginning of that file. Either you've been hacked, or you had a mod installation not go so well.
