Okay, apologies. I thought you were “error logging” in a different way.

With “WP_DEBUG_LOG”, the file is saved in the “wp-content” directory. The filename should be “debug.log”. You can read more about it on the WordPress Codex for Debugging.

BUT… If you are seeing these errors on your dashboard, then you don’t really need to look at the debug log file. The error will stop displaying in your dashboard whenever the faulty code is removed/deactivated.

Hi Stephanie,

It sounds like you have a plugin (or theme option) which is trying to use the WP_Error class, but it using it incorrectly.

I would start by deactivating ALL plugins; and see if the error persists.

If you are unable to log into your admin panel to deactivate plugins; then you will need to use either FTP or your hosts cPanel software (via your browser) to gain access to your file directories.

Once there, navigate to the wp-content directory. You will see a folder named plugins. Rename this folder TEMPORARILY to something like plugins_temp.

Now, go back and log into your admin panel. You should notice all plugins are gone… but you can now re-access your website.

Now, reactivate a few plugins… and make sure you are able to continue browsing your site with no errors. When you know you’re good… activate a few more plugins; and repeat.

Eventually you should find a plugin that is throwing the error. You will need to contact that plugin author for assistance.

Lastly, if NO plugins were are fault, the issue might be with your theme. Try switching to the default 2016 WordPress theme; and see if the issue persists. If it does not, then it is your theme.

Please let us know how you do.

Hi,

You are probably using an outdated plugin or theme option that is still calling the deprecated add_object_page() function.

I would start by deactivating all plugins; and clearing the error log. Next, reactivate a few plugins, and click a few pages of your website admin panel (just to see if error reproduces).

If the error does NOT show, go back and activate a few more plugins, again repeating the clicking admin pages, and again check the error log.

If you do this for ALL plugins and still show the error; then it may be in your theme. In this case, try switching to the default 2016 theme, clearing the error log, and clicking admin pages. Again, check the log.

Eventually you will find a plugin (or theme option) that is causing the error.

PS:
That error notice is not very helpful as it does not provide the location of the file that is calling the deprecated function. It only tells you the function name; so you have to dig for answers.

Let us know how you do.

😉 You’re welcome!

Hi,

If you mean creating an additional metabox for the “add/edit post” and/or “add/edit page” screens; then you’ll want to review this Codex page:
https://codex.wordpress.org/Plugin_API/Action_Reference/add_meta_boxes

You may try something like this:

<section class="news-list">
   <?php $the_query = new WP_Query( 'posts_per_page=5' ); ?>
   <?php while ($the_query -> have_posts()) : $the_query -> the_post(); ?>

         <div class="news-list__item" data-scroll-watch>
            <a href="<?php the_permalink() ?>">
               <div class="news-list__item__image" data-bg-img="<?php the_post_thumbnail_url(); ?>"></div>

                  <?php
		  foreach((get_the_category()) as $category) {

		      // Define default color
		      $bg_color = 'CCC';

		      // Check if slug matches one of our slugs
		      if ($category->slug == 'thoughts')
		          $bg_color = '#F00';
		      if ($category->slug == 'social')
		          $bg_color = '#000';
		      if ($category->slug == 'story')
		          $bg_color = '#EEE';

		      echo '<div class="news-list__item__text" data-bg-color="' . $bg_color . '">';
                      echo '<p>' . $category->cat_name . '</p>';
                   }
				   ?>
               <p><?php the_title(); ?></p>
            </div>
         </a>
      </div>

   <?php
      endwhile;
      wp_reset_postdata();
   ?>
</section>

It appears your theme is using a function named the_post_thumbnail_caption(); which was included in WordPress core in version 4.6.

I would suggest contacting your theme author; and explaining the situation. Since this function is now included in WordPress core; they may want to remove the function; or re-write it.

There is also a thread on Stack Overflow explaining the function inclusion into WordPress core (and how to modify). See THIS topic; 2nd response.

Perhaps something like this?

$cat_id = get_category( get_query_var( 'cat' ) );

$categories = get_categories(
    array( 'parent' => $cat_id )
);

This should give you an array of all child categories of the parent. Then, all you need to do is loop them, and extract what info you need.

foreach( $categories as $cat ) {

    echo '<li>'.$cat->name.'</li>';
}

That should give you a list of all child categories names. You can use ‘var_dump( $cat )’ inside the loop to see what other values you can retrieve. I know you can also use `$cat->description’ to get the category description.
