Thanks for your help. At the end the function apply_filters did the trick. I replaced my last line of code echo wpautop($newcontent); with echo apply_filters( 'the_content', $newcontent); and it worked.

I’ve found the problem. The theme uses this code for the content

while (have_posts()) :
	the_post();
	$content    = get_the_content();
	$newcontent = add_anchors($content);
	echo wpautop($newcontent);

It doesn’t use the function the_content because the custom function add_anchors that adds anchors to all the H2 headings, in order to link them to a TOC.

Do you think there is a way to make the plugin work with this code?

Hi Ben,

thanks for helping. I gave a try by switching the theme to a WordPress standard one and the shortcode works properly. So as you said, it’s a theme issue.

I dig into it. Thanks for the input.

Thank you for having solved it so quickly. Great job!

Hi Alex, thanks for your reply. My URL is https://invalencia.info

Sorry, I’ve changed the textdomain and it was the problem.

Ok, I found the solution. Just for your information, there is a call to wp-blog-header.php that goes to the root installation, by changing to the actual installation everything works.

Thanks for your time.

Hi kjodle,

fist of all let me thank you for your help. I’ve discovered the problem, but I’m unable to find a solution. The problem is that WordPress is installed in a subfolder of another WordPress installation. wpdb is reading the root website database, instead of the subfolder installation database. How can I tell him to read the right db?

No. Simply the data don’t appear.

I’m having the same problem. My website have been attacked and I think this is related to the attack somehow.

Did you find a solution?

The problem follows the latest Nextgen Gallery updating.

Same here. It was working until few days ago, but now it seems impossible. Same error message: Warning: imagecreatetruecolor() [function.imagecreatetruecolor]: Invalid image dimensions in /home/thesmart/public_html/wp-content/plugins/nextgen-gallery/products/photocrati_nextgen/modules/nextgen_data/class.ngglegacy_thumbnail.php on line 895

Any chance to create a small dashboard for the single users with the listing of the tests already taken?

Thanks for your help.

Thanks. It’s perfect for what I was looking for.
