Waarschuwing – Fout “Kan headerinformatie niet wijzigen”.

Dit gebeurt wanneer de fout wordt veroorzaakt door een gebroken code in de header van uw pagina. Het bericht ziet er bijvoorbeeld zo uit:

Warning: Cannot modify header information - headers already sent by (output started at /yoursite/wp-config.php:1) in /yoursite/wp-includes/pluggable.php on line 1251 

Warning: Cannot modify header information - headers already sent by (output started at /yoursite/wp-config.php:1) in /yoursite/wp-includes/pluggable.php on line 1254

Oplossingen:

1e oplossing

De waarschuwing kan headerinformatie niet wijzigen – headers die al per ongeluk zijn verzonden kunnen op verschillende manieren worden opgelost. Ga eerst naar wp-config.php en voeg deze code toe op de eerste regel:

ob_start(); 

error_reporting(0);

Maak de cache van de browser schoon (als je een cache-plugin hebt geïnstalleerd, probeer die dan door te spoelen) en kijk of het probleem is opgelost.

2e oplossing

De oplossing voor mij was dat de windows locale niet op UTF8 stond, en het uitpakken van de bestanden lijkt de boel te hebben verpest.

Looking for a Wordpress transfer from site A to site B, I found back Andrei from Wesites Seller on Google.He was very proactive in his approach, came with hundreds of ideas and lifetime experiences from other migrations. He knows the wordpress, the hosting and php database as the back of his pocket.And we worked out this migration very smooth. Together we solved it, and myself and my business are very pleased with his approach.100% recommendation & kudo's from out of Belgium!

Websites Seller built my resume site. Deliverables were quickly completed, and I was asked for my feedback at each stage of development. All feedback I gave was implemented in a short time.Another great thing is that he comes with smart solutions, regarding stuff which I didn't initially think of (site security, Google site speed optimization and so on). Basically, he was great, staying in touch, keeping me updated and paid attention to what was most important for my site.Overall, I am very happy with the work done. I highly recommend this developer!
