Advarsel – Fejl: “Kan ikke ændre headeroplysninger”

Dette sker, når fejlen udløses på grund af en ødelagt kode i sidens header. Meddelelsen ser f.eks. sådan ud:

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

Løsninger:

1. løsning

Advarslen kan ikke ændre headeroplysninger – headere, der allerede er sendt ved fejl, kan løses på forskellige måder. Først skal du gå til wp-config.php og tilføje denne kode på den første linje:

ob_start(); 

error_reporting(0);

Rens browserens cache (hvis du har et cache-plugin installeret, skal du prøve at rense det), og se, om problemet er løst.

2. løsning

Løsningen for mig var, at Windows locale ikke var på UTF8, og udpakning af filerne ser ud til at have ødelagt tingene.

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!
