headers already sent
ik weet dat deze vraag vast vaker gesteld is en ik heb ALLE pagina's al bekeken op whitespace voor EN na de open en closing tag van php maar kan niks vinden.
de error melding is alsvolgd:
Warning: Cannot modify header information - headers already sent by (output started at controvi.com/public_html/mu/index.php:11) in controvi.com/public_html/mu/layoutpart/content/logout.php on line 21
en dit is de code van logout.php:

en aangezien ik al wel gehoord heb dat je de headers niet mag neerzetten na de html (of zoiets) maar dit wel werkt lokaal (ontwikkel omgeving ) maar niet op mijn gebruikers omgeving, wil ik wel eens weten wat er nou aan de hand is.
Ik heb het probleem helemaal opgelost :)
ik heb de index nu als volgt gemaakt omdat wat ik al zei over de de header voor de html plaatsen .
