Notice about deprecated constructor method in include folder

Make sure all your plugins/theme are up to date.

Try:
– deactivating ALL (yes all) plugins temporarily to see if this resolves the problem (plugin functions can interfere). If this works, re-activate them individually (one-by-one) to find the problematic plugin(s).
– If you can’t get into your admin dashboard, try resetting the plugins folder by FTP. Sometimes, an apparently inactive plugin can still cause problems. Also remember to deactivate any plugins in the mu-plugins folder (if you have created such folder). The easiest way is to rename that folder to mu-plugins-old.
– switching to the unedited default Theme (Twenty Sixteen, etc.) for a moment using the WP dashboard to rule out any theme-specific issue (theme functions can interfere like plugins). If you don’t have access to your admin area, use FTP , or your web-host’s cPanel or whatever file management application your host provides (no Dashboard access required). Navigate to /wp-content/themes/ and switch to the default theme by renaming your current theme’s folder by adding “-old” to the end of the folder name. Alternately, you can remove other themes except the default theme. That will force your site to use it.

– If all the above steps do not resolve the issue, then try MANUALLY updating. Download a fresh copy of the WordPress .zip file to your computer, unzip it, and use that to copy up all files and folders EXCEPT the wp-config.php file and the /wp-content/ directory. You may need to delete the old wp-admin and wp-includes folders and files on your server before uploading the new ones. Read the Manual Update directions first.
– Backup: If you haven’t already done, always backup everything (including your database) before doing any actions, just in case something really goes wrong.

Thank you Tara, I will do the above and let you know the result. Appreciate you advise.

you are welcome ??

All plugin removed – only child theme active and I get this error Warning: call_user_func_array() expects parameter 1 to be a valid callback, function ‘search_filter’ not found or invalid function name in /var/www/html/training.pickford.intra/training/wp-includes/plugin.php on line 601
The only thing I can think of is that I created a custom post plugin and below is my code:
function courses_custom_posttypes() {
//adding course post type
$labels = array(
‘name’ => ‘Courses’,
‘singular_name’ => ‘Course’,
‘menu_name’ => ‘Courses’,
‘name_admin_bar’ => ‘Courses’,
‘add_new’ => ‘Add New’,
‘add_new_item’ => ‘Add New Course’,
‘new_item’ => ‘New Course’,
‘edit_item’ => ‘Edit Course’,
‘view_item’ => ‘View Course’,
‘all_items’ => ‘All Courses’,
‘search_items’ => ‘Search Courses’,
‘parent_item_colon’ => ‘Parent Courses:’,
‘not_found’ => ‘No courses found.’,
‘not_found_in_trash’ => ‘No courses found in Trash.’,
);

$args = array(
‘labels’ => $labels,
‘public’ => true,
‘publicly_queryable’ => true,
‘show_ui’ => true,
‘show_in_menu’ => true,
‘menu_icon’ => ‘dashicons-welcome-learn-more’,

‘rewrite’ => true,
‘capability_type’ => ‘post’,
‘has_archive’ => true,
‘hierarchical’ => false,
‘menu_position’ => 5,
‘supports’ => array( ‘title’, ‘editor’, ‘thumbnail’,’author’, ‘post-formats’),
);
register_post_type( ‘courses’, $args );
}
add_action( ‘init’, ‘courses_custom_posttypes’ );

// Flush rewrite rules to add “review” as a permalink slug
function courses_custom_flush() {
courses_custom_posttypes();
flush_rewrite_rules();
}
register_activation_hook( __FILE__, ‘courses_custom_flush’ );
/*create taxaonomy*/

function course_taxonomy() {
register_taxonomy(
‘courses_categories’, //The name of the taxonomy. Name should be in slug form (must not contain capital letters or spaces).
‘courses’, //post type name
array(
‘hierarchical’ => true,
‘label’ => ‘Course Category’, //Display name
‘query_var’ => true,
‘rewrite’ => array(
‘slug’ => ‘course’, // This controls the base slug that will display before each term
‘with_front’ => false // Don’t display the category base before
)
)
);
}
add_action( ‘init’, ‘course_taxonomy’);
/*change the permalink */

function filter_post_type_link($link, $post)
{
if ($post->post_type != ‘courses’)
return $link;

if ($cats = get_the_terms($post->ID, ‘courses_categories’))
$link = str_replace(‘%courses_categories%’, array_pop($cats)->slug, $link);
return $link;
}
add_filter(‘post_type_link’, ‘filter_post_type_link’, 10, 2);

Did I do something wrong?

Thank you

And this is how I display it:
get_header();
global $accesspresslite_options;
$accesspresslite_settings = get_option( ‘accesspresslite_options’, $accesspresslite_options );
?>

<section id=”primary” class=”content-area”>

<?php if ( have_posts() ) : ?>

<h1 class=”page-title”>Courses</h1>
<?php
// Show an optional term description.
$term_description = term_description();
if ( ! empty( $term_description ) ) :
printf( ‘<div class=”taxonomy-description”>%s</div>’, $term_description );
endif;
?>
</header><!– .page-header –><nav class=”nav-cat”>

The problem was in child’s them function.php. I had some unused codes which causing some of the warning and one plugin that also was not in use, but activated for some reason.

Thank you some much for your time and great detailed advise.
