Well, the error message really says it all, it's just worded a bit opaquely! Basically, setting a cookie uses an HTTP header, and all HTTP headers have to be sent before your actual page content -- and the error message is saying that you can't send an HTTP header at line 10 of your script, because you started outputting your page content at line 8. > Warning: Cannot send session cache limiter - headers > already sent (output started at > /var/www/html/prueba/index.php:8) in > /var/www/html/prueba/index.php on line 10 Same thing, but for a cache limiter header. You need to re-order your script so that the header requests come before the start of real output. Cheers!
