Breadcrumbs and theme conflicts

I have tried other plugins and their locations, but even after creating a unique name – the error still exists and it appears on random posts on my sidebar (where I have the other loops). I don’t know what you mean by “partially deleted locations”. I have deleted locations in the past.

And this happens only if I visit the location’s address (the post/page itself). I have loops for a sidebar “latest news” section where I pull the latest posts from different categories. That’s where the error shows up on random (not on all “latest-news” posts).

I’m running the site on a local xampp installation and I have nowhere to upload it to show you, I’ll make screenshots and paste you the loop code.

Here is how it looks:

Looking at one of the screenshots (Test Title), an upcoming events list is being generated but for another location, not the one that I have currently opened. My text excerpt is “Just another test post to check a few things” and then the Upcoming events part comes up. It would probably come up in the other one as well but it has a longer excerpt and no place to add more text.

Other sections are fine, like this one:

<?php
$args = array(
    'post_type' => 'review',
    'posts_per_page' => 1,
    'cat' => '28',
);
$q = new WP_Query( $args);

if ( $q->have_posts() ) {
    while ( $q->have_posts() ) {
    $q->the_post(); ?>
            <a href="<?php the_permalink(); ?>" title="<?php the_title_attribute(); ?>"><?php 
        the_title(); ?></a>
    <?php if ( has_post_thumbnail() ) : ?>
            <a href="<?php the_permalink(); ?>" title="<?php the_title_attribute(); ?>">
                <?php the_post_thumbnail('medium'); ?>
            </a>
            <?php endif; ?>
                <?php
        the_excerpt(); ?>

<?php

$the_cat = get_the_category();

$category_name = $the_cat[0]->cat_name;

$category_link = get_category_link( $the_cat[0]->cat_ID );

?>
        Posted in <a href="<?php echo $category_link ?>" title="<?php echo get_the_category( $id )[0]->name ; ?>">
        <?php echo get_the_category( $id )[0]->name ; ?></a>
Posted on <?php echo get_the_date(); ?> by <?php the_author_posts_link(); ?>
<?php
    }
    wp_reset_postdata();
}
?>

I have cleaned the divs and text formatting to make it easier to read. This is the loop I use for the book review section. I was wondering if somehow the category IDs could be the problem. I could change those to category slugs instead.

No, I’ve never run shortcodes. The side loops (latest-article-from-a-category sections) are part of the footer.php, while the main loop for the location is indeed in a custom single-mc-locations.php file.

<?php
 get_header();
?>

<?php
    if( have_posts() ){

        while( have_posts() ){
            
            the_post();
            get_template_part( 'template-parts/content', 'location' );

        }
    }
?>

<?php
 get_footer();
?>

And here is the content for the template part “location”:

<?php           
        the_title(); 
    ?>
<?php if ( has_post_thumbnail() ) : ?>
        <?php the_post_thumbnail('large'); ?>
<?php endif; ?>
<?php
the_content();
?>
<?php	
edit_post_link( __( 'Edit Location', 'textdomain' ), '[', ']' ); ?>

I stripped down all “cosmetic” divs for easier reading. I too fail to see what the relationship between these loops are. And keep in mind that this error pops up randomly on different loops. After uploading a new article today, it removed itself from the book reviews section screenshoted in my previous post and appeared in another one:

Whenever I go to localhost/mc-locations/locationname it redirects me to localhost/locations/locationname and the result is the same. Could it be something left over from other event plugins, even though the error is directing towards My Calendar file? I can get over not having location pages, but that phantom error is bizarre.

Thank you for the time. My locations will remain disabled and I will remove all links to them. This is still the best plugin I’ve tried, at least for my needs so thank you.
