i had installed the 4.0.5 Version of the plugin and have made the changes in the wp-config.php and .htaccess file, who are quoted in this post:
When opening the sitemap, it displays the following error:
XML-Verarbeitungsfehler: XML- oder Text-Deklaration nicht am Beginn der Entität
Zeile Nr. 2, Spalte 1:
I am Using WP 3.9 on a NginX Server. The SEO Plugin is "All in one SEO Pack" ...
I also tried to downgrade the plugin, but this causes that the page completely went down.
Maybe someone can help ??
Many thanks in advance
