[Support request] PHP Error with GP Pro Plugin on Custom Author.PHP Page

[Thomas]

Hey GP Team.

I have a weird error occuring. I am currently receiving this following notice when I have GP Premium enabled on my Author.php custom file:

Notice: Undefined offset: 0 in /home1/monadno7/public_html/staging/wp-includes/class-wp-query.php on line 3300

I have tried disabling every other plugin and the error isn’t there until I activate GP Premium :(.

Hoping you all could give a clue as to a solution!

Here is the code of my Author.PHP file, so it could be something in there, although it is quite basic:

<?php
/**
 * The template for displaying Archive pages.
 *
 * @package GeneratePress
 */

if ( ! defined( 'ABSPATH' ) ) {
	exit; // Exit if accessed directly.
}

get_header(); ?>

	<div id="primary" <?php generate_do_element_classes( 'content' ); ?>>
		<main id="main" <?php generate_do_element_classes( 'main' ); ?>>
			<?php
			/**
			 * generate_before_main_content hook.
			 *
			 * @since 0.1
			 */

			$curauth = (isset($_GET['author_name'])) ? get_user_by('slug', $author_name) : get_userdata(intval($author));
			do_action( 'generate_before_main_content' );

			echo ('<div class="customAuthorPage">');
			echo ('<p>' . esc_attr($curauth->nickname) . '</p>');
			echo('</div>');
						

			$args = [
				// parameters go here
			];
			$query = new WP_Query( $args );
			if ( $query->have_posts() ) { 
				while ( $query->have_posts() ) {
					$query->the_post();
					// display the post
					the_title();
					the_content();
				}
				wp_reset_postdata();
			} else {
				esc_html_e('');
			}
			

			/**
			 * generate_after_main_content hook.
			 *
			 * @since 0.1
			 */
			do_action( 'generate_after_main_content' );
			?>
		</main>
	</div>

	<?php
	/**
	 * generate_after_primary_content_area hook.
	 *
	 * @since 2.0
	 */
	do_action( 'generate_after_primary_content_area' );

	get_footer();

Thank you for the help!

Hi Thomas,

Not sure if I fully understand.

The error is pointing to a class-wp-query.php file in wp-includes folder which is a WordPress folder and not a theme folder.

[Thomas]

Yeah that’s whats confusing me, as the error goes away when GP Premium is disabled….

[Thomas]

Ohhhhh I think I might’ve figured it out.

So I have a custom element that assigns the Featured Image as a page header along with a fallback. Since author.php (and by extension archive.php) don’t have featured image capability, I think it sends this error along.

[Thomas]

Another update, sorry for the many posts in a row.

So, I figured creating a new header JUST for the archives without setting it to look for a Featured Image would solve this, but it didn’t. Even without a image in the header it still throws this error/warning. I’m not sure what’s causing it, but if you know anything or if I figure it out i’ll send a notice 🙂

[Leo]

Do you get the error without your own author.php file?

[Thomas]

Hey Leo, nope, it does appear to only be related to the WP Users archives and author.php. Although, I don’t have any other archive files I think to test. Although, the error doesn’t pop up when I load the administrators profile page, just anyone else. So something to do with users then I presume!

[Tom]

Hi there,

Not sure why GP Premium would have anything to do with this. What happens if you deactivate all of the modules in “Appearance > GeneratePress”?

[Thomas]

Hey Tom, getting the obvious out of the way in that disabling Elements gets rid of it, I found the following:

Backgrounds: Error still shows
Blog: Error still shows
Colors:Error still shows
Copyright: Error still shows
Disable Elements: Error still shows
Menu Plus: Error still shows
Secondary nav: Error still shows
Typography: Error still shows

So it seems to be realted to the “Elements” module, strangely.

[Tom]

In that case, it’s likely you’ve added some code inside of an Element that’s causing the error.

What happens when you “Draft” each element?

[Thomas]

Hey Tom

When I draft the element, the error goes away (and so does the header).

Currently I have the header set up like this:

<!–comment–!>

But even if I change it to something like <h1>test</h1> the error would come back. If I put nothing in the text / html area, the error goes away (but so does the header image).

I can just custom code a header into this, just figured i’d give you a heads up, although maybe this issue is relegated to just me lol.

Hi there,

On your author.php template, what happens if you temporarily remove this line?

$curauth = (isset($_GET['author_name'])) ? get_user_by('slug', $author_name) : get_userdata(intval($author));

and these.

echo ('<div class="customAuthorPage">');
echo ('<p>' . esc_attr($curauth->nickname) . '</p>');
echo('</div>');

Can you test again if the error occurs when you add any element?

Also,

Can you include the $args values?

[Thomas]

Same error still shows up :(. Here’s my query:

		$args = [
			// parameters go here
		];
		$query = new WP_Query($args);
		if ($query->have_posts()) {
			while ($query->have_posts()) {
				$query->the_post();
				// display the post
				the_title();
				the_content();
			}
			wp_reset_postdata();
		} else {
			esc_html_e('');
		}

There’s another interesting case of a 0 showing up that I can’t explain. In the private area I have included a link but if you run a search you’ll get a result, but then a random “0” at the end. I doubt its related but it might give a clue? But I don’t think that is GP related.

[Elvin]

Any reason why your WP_query arg is empty?

I believe that’s where the error is coming from.

Set your args appropriate to the author page. https://developer.wordpress.org/reference/classes/wp_query/

[Thomas]

Was using author.php more as a template then actually seeing any of the posts, so that’s why it was left empty, if that makes sense!

Unfortunately that didn’t do it either :(. I tried it a couple of ways:

$args=[
'author' = $authorID
]

and tried it like this:

		$query = new WP_Query(array('author'=>$authorID));

but it might just be a glitch with the query itself and this page? Because I tried to pass some content into the while haveposts loop and nothing showed up; similiary if I remove the wp_query, the page still works, the error is still there.

So i’m not sure lol. Do you folks have a author.php page you used that I could experiment with? Even if its just boilerplate.

Thanks!
