onPaymentNotification() - Internal Server Error

Hello.

I am trying to access this URL:
www.4u2.co.il/temp.php?notif_payment=ban...pl=component&lang=he

and i run into a 500 Internal Server Error page, temp.php got has a permission of 777 and i checked the error_log and it says:

[26-Jul-2011 16:16:16] PHP Warning: include(/home/ucoil/public_html/components/com_hikashop/controllers/index.php.php) [<a href='function.include'>function.include</a>]: failed to open stream: No such file or directory in .../public_html/components/com_hikashop/hikashop.php on line 43
[26-Jul-2011 16:16:16] PHP Warning: include() [<a href='function.include'>function.include</a>]: Failed opening '.../public_html/components/com_hikashop/controllers/index.php.php' for inclusion


What does it means? why does Hikashop searches for index.php.php which does not exsist?
thanks in advance.

That would mean that the ctrl variable has the value index.php

It must come from the temp.php file. What do you have in it ?

only got some html:

<html>
<body bgcolor="#FFFFFF">
</body>
</html>

How can it have the value of index.php?

Problem solved.
Cpanel does not approve permisstion of 777.

Thanks for the help
