Can not see custom content type to add to library

I have Sharepoint 2016 on prem version. I have created a library with Infopath form for employees to complete. Once the form is submitted a workflow needs to assign a task for someone else to Acknowledge receipt. The assign task in the workflow make use of a custom content type. I’ve created the custom content type with Workflow task as parent.
I need to add that content type to the library in order for the workflow to assign the task. But when I go to Library/settings/ and click on ‘add existing content type’ it does not show the newly created content type in the list of available content types. Why would that be? (I also noticed some other content types also does not show)

Shortcode result appears above page content

Hi there I’m having troubles with some shortcode because it’s result appears above the page content when it should appears instead the place where the shortcode is placed.
This is the shortcode code…

if (!defined('ABSPATH')) exit;

/* creacion del shortcode (cotizador id="") */

function cotizador_shortcode($atts)
    /* le pasamos los argumentos al shortcode dentro de un array */
    $args = array(
        'post_type' => 'vehiculos', /* se toma de post_type.php */
        'id' => $atts('id')
        // 'familia' => $atts('familia')
    $cotizador = new WP_Query($args); /* sirve para imprimir el post_type en el shortcode */
    $single_car_query = cotizador_car_query($args('id'));
    // $title_query = cotizador_query_select($single_car_query('post_id'));
    $precio = $single_car_query('car_price');
    $enganche = $single_car_query('car_price') * 0.10;
    // echo "<pre>";
    //    var_dump($enganche);
    // echo "</pre>";


    <form name="cotizador_enviar" id="cotizador_enviar">
        <div id="cotizador" class="cotizador">
            <table class="table table-hover">
                        <th scope="col">Modelo</th>
                        <th scope="col">Precio</th>
                        <th scope="col">Enganche</th>
                        <th scope="col">Bono</th>
                        <td><?php echo esc_attr("$". $precio); ?></td>
                        <td><?php echo esc_attr("$". $enganche); ?></td>

add_shortcode('cotizador', 'cotizador_shortcode');

As you can see, the result is HTML, but when I place the shortcode in the page content it looks like this:
Shortcode error

When the result should appear below the picture as you can see here in the wp-admin:
wp-admin shortcode placed

I know that if we use “echo” this happen and can be fixed using “return” but this only works for variables (I guess) but in my case the result is not a variable so I’m confused


8 – Exception handling for incorrect content type for request in custom REST API plugin

I have created a custom REST API plugin for an endpoint. I have set the accepted format to json using the configuration options. This works. However, if we set the content-type to something other than application/json I am getting a 500 error.

I am seeking to know how this exception can be handled more gracefully. However, what is preventing this is the fact that I am not able to get the Request object in the plugin code.

I tried extending the default EventSubscriber services but they do not seem to be of help. I am seeing that this seems to be an open issue in

I am thinking of altering the route and set the default format to json as in manually added custom routes but open to better ways.

Any help would be appreciated.

How do I delete content from a PDF file?

I’ve tried the first 5 or so results on Google for PDF editors, and none of them allow me to delete existing PDF content, they only allow me to add new content on top of the existing content.

I’ve also tried opening the PDF in LibreOffice Draw, but the text does not look correct and overflows.
