can anybuddy help me
Thanks in advance

 

Holy CRAP, that's some awful code. But I would first and foremost check to see if the ./libs/link_summary.php (which seems to be the only content supposed to show) actually exist and is fetchable - change the include() to include_once() or require_once() - and for deity's sake, turn on PHP-errors while developing so errors and warnings get shown.
Secondary - throw out Pligg / Smarty / whatever template crap you're using.

 

Hi thanks for reply but i dont understand what you say
can you pls describe solution step by step
Thanks

 

I did.
First: check to see if the file link_summary.php exists in the folder you're trying to include it from - I only got a 403/404 error when I tried accessing it myself.
Second: turn on PHP-error display when you develop, so PHP shows you errors and warnings when something is wrong.
Third: get rid of that hopeless code-bloat that is Pligg / SMARTY.
Four: Take out the redirect-garbage you have in the code - that might very well be what's causing the errors.
Five: learn to code before you do try to make something involving (gasp!) code.

 

Add the following few lines at the beginning of index.php:

<?php
ini_set('display_errors', 1);
ini_set('display_startup_errors', 1);
error_reporting(-1);

function str_ends_with($haystack, $needle) {
...
...

PHP:

and let us know if you see any errors when loading the page.

 

Thanks for reply but there are no any effect after change in index.php
Only white blank page are show
Please help me
Thanks

 

Try this: comment out all the header()-lines, and substitute them with echo 'this is supposed to do <what the headerline says>'; - Then you'll probably at least see where the error is originating.

 

Thanks For your valuable solutions
but problem are shutout and website work great
actuality this is error log file problem. just empty error log file and website work great .
Thanks

 

Uhm, no, it doesn't. If a full error-log is causing you problems, then you have an insane amount of errors - which is in no way a good thing.

 

You are right sir But the problem are shutout and website work fine.
i seen in Pligg support about error log file and many people have solution with empty error log file.

 

*headdesk* Okay. Fine. Use that trainwreck of crappy code, and empty your error log at regular intervals. Perfect solution to the problem at hand. *shakes head*
