Jag kan bara lite html, försumbart med php och just ingenting om apache webserver.Important Warnings
The validator has found the following problem(s) prior to validation, which should be addressed in priority:
1. Warning Conflict between Mime Type and Document Type
The document is being served with the text/html Mime Type which is not a registered media type for the XHTML 1.1 Document Type. The recommended media type for this document is: application/xhtml+xml
Using a wrong media type for a certain document type may confuse the validator and other user agents with respect to the nature of the document, and you may get some erroneous validation errors. How to fix this problem? One of the following techniques should help:
* If you are serving a static file on a Web server, changing its extension should help. Use e.g .xhtml for XHTML or .mathml for MathML.
* You may need to reconfigure your Web server. This Setting up MIME Types tutorial has instructions for Apache, Tomcat and IIS.
* If the document is generated dynamically, the scripting language should allow you to set up the mime type: this article on MIME Types and Content Negotiation has examples in PHP, Perl, and ASP.
Kan någon säga mig vad som är bra att göra? I annat fall kan jag säkert läsa mig till det, men om du sitter inne med svaret så...
Till saken hör att detta verkar vara ett nytt "fel" på en sida som var fullt godkänd i våras.
