Ivoinperu,
Sounds like you may be running an older version of PHP. Try the solution in this blog post. This fix is also being incorporated into the next version of WP HTML Sitemap.
wmsedgar,
made the change as described in the blog post and it works like a dream.
Thank you very much !
wmsedgar, I have the same problem.
I looked at the blog post you sent but I can’t find the wp-html-sitemap.php file on my server.
Any ideas?
I found the file, replaced
add_shortcode( ‘wp_html_sitemap’, ‘wp_html_sitemap_shortcode::start’ );
With
add_shortcode( ‘wp_html_sitemap’, array(‘wp_html_sitemap_shortcode’, ‘start’) );
But I still get the code instead of the content.
I’m using 3.4.1 WP, Yoast SEO, Kimili Flash Embeded and Simple 301 Redirect plugins.
I am having the same problem, and the same issue with the suggested fix. This plugin does not work, clearly.
The problem was in the server settings, apparently. You need to make sure your host server support the plugin. I changed hosting and the plugin worked (moved from HostGator to GoDaddy).
