    I am sorry to ask but… If I dont set a file to a category, I get a serious error and the nav doesnt work:

    Warning: Invalid argument supplied for foreach() in –removed for privacy–/wp-content/themes/x-child/functions.php on line 83

    According to line 83 says this:
    foreach ( $categories as $category ) {

    Hi there,

    Try wrapping it with if condition, like this,

    if ( is_array( $categories ) && count($categories) > 0 ) {

foreach ( $categories as $category ) {
....
}

}

    Thanks!

    Where am I putting this code?

    I am not sure how to “wrap” it.

    I put

    if ( is_array( $categories ) && count($categories) > 0 ) {

foreach ( $categories as $category ) {

    before

    function x_integrity_entry_meta() {

    and then at the tail end of the code, I put the

    }

}

    and the categories were not showing at all.

    Hello There,

    Thanks for the updates.
    Could you please post the contents of your child theme’s functions.php file?

    For the meantime, please find this block:

    
      foreach ( $categories as $category ) {
        $categories_output .= '<a href="'
                            . get_term_link( $category->slug, 'portfolio-category' )
                            . '" title="'
                            . esc_attr( sprintf( __( "View all posts in: &ldquo;%s&rdquo;", '__x__' ), $category->name ) )
                            . '"><i class="x-icon-bookmark" data-x-icon=""></i> '
                            . $category->name
                            . '</a>'
                            . $separator;
      }

    And replace it using this block instead:

    
  if ( is_array( $categories ) && count($categories) > 0 ) {
  	foreach ( $categories as $category ) {
		$categories_output .= '<a href="'
                    . get_term_link( $category->slug, 'portfolio-category' )
                    . '" title="'
                    . esc_attr( sprintf( __( "View all posts in: &ldquo;%s&rdquo;", '__x__' ), $category->name ) )
                    . '"><i class="x-icon-bookmark" data-x-icon=""></i> '
                    . $category->name
                    . '</a>'
                    . $separator;
  	}
  }

    Hope this helps.
