Please help!Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent

[yvettekukoja]

i installed PayPal Website Payments Pro, U.K. Edition, with PWA (http://addons.oscommerce.com/info/5442) contribution and now I am encountering warning messages on every page

www.lamimini.com/catalog

>_<

 

Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /homepages/34/d215854678/htdocs/catalog/includes/application_top.php:2) in /homepages/34/d215854678/htdocs/catalog/includes/functions/sessions.php on line 102

 

Warning: Cannot modify header information - headers already sent by (output started at /homepages/34/d215854678/htdocs/catalog/includes/application_top.php:2) in /homepages/34/d215854678/htdocs/catalog/includes/functions/general.php on line 32

 

 

Anyone knows how to fix this? Any help is greatly appreciated.

/homepages/34/d215854678/htdocs/catalog/includes/functions/sessions.php on line 102

 

so on sessions.php line 192 is generating some warning either place an @ over there or fixit.

 

Definitely an issue with register globals and session.

Actually it's not sessions.php that the problem - look closely at the error

Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /homepages/34/d215854678/htdocs/catalog/includes/application_top.php:2) in /homepages/34/d215854678/htdocs/catalog/includes/functions/sessions.php on line 102

 

You may have a blank line or a space before the <?php in application_top.php - delete anything before this
