yes, you could do like that. it should work.
but did you try also to remove the query_var parameter?

Try to remove the the query_var parameter when you are registering the topic taxonomy.

The possible values of query_var should be false or a string.
If you don’t define query var it defaults to taxonomy’s name.

it seems the problem is that wp_list_categories is writing the taxonomy name with the first letter capitalized. If it’s not capitalized it works ok:

But I don’t understand why it’s happening.

No, that’s a wrong approach.

Where did you define the function wp_list_categories? In what file?

I think it’s related to the way you are writing the urls.

The links of the topics should be somethink like this:
https://client.ocularconcepts.us/welead/topic/personal-leadership/

About the other problem of the taxonomies, in what pages can I check that problem?

About the other problem, if you’re talking about the warning errors with the header, usually is because you have some extra spaces before an opening <?php tag or after a closing ?> tag. It generally happens in wp-config.php.

It’s a big risk… anyone can read this forum and do some harm to your site/server.

Do you have an url where I can see that?

yes, it should go to taxonomy.php.
you can also create a taxonomy-topic.php, if you want to create a template only to topic taxonomy.

What is happening? Nothing shows up or another template is being loaded?

good ??

In Appearence > Edit CSS, you add the following css:

#access {
	background: white;
}

That will make the menu bar background color white.

To list all categories from topic taxonomy:

<ul>
<?php wp_list_categories( 'taxonomy=topic' ); ?>
</ul>

If you want to show all the categories, even the ones that are empty add the parameter hide_empty=0.

same ideia wpyogi ??

What if you define a bigger excerpt length and put the text inside a div with overflow: hidden ?
You could define a line-height for that div, and the height would be a multiplier of the line-height, so that a line of text wouldn’t appear in half.

Just an ideia…
