The plugin doesn't cleanly uninstall

Hi,
Try to activate the default theme Twenty and see if you have the same issue. Please let me know if yes or no.
Have a nice day.

I tested with Storefront (Version : 2.0.0) the default Woocommerce theme.
The issue comes from you uninstall.php file. You call in this file a variable which is not defined, it’s why I have in the debug.log: WordPress Incorrect table name '' for these piece of code in your uninstall.php:

//remove any additional options and custom table
$sql = "DROP TABLE <code>" . $wpdb->yith_wcwl_items . "</code>";
$wpdb->query( $sql );
$sql = "DROP TABLE <code>" . $wpdb->yith_wcwl_wishlists . "</code>";
$wpdb->query( $sql );

And the other problem is that the Yith options are not remove in the DB.

Could you please forward this issue to the plugin developers?

Hi Chrystl,

sorry for my late response; we had plenty of things to take care of, and I’ve managed to process this request only today

I checked your report, and fixed the problem in uninstall.php

Besides, I improved uninstall code to work on network installations (codex doesn’t take this case into account, by the way)

You’ll find these improvments in the next plugin release; anyway, if you want to test them right now, you can try to replace the uninstall.php code with what follows

<?php
/**
 * Uninstall plugin
 *
 * @author Your Inspiration Themes
 * @package YITH WooCommerce Wishlist
 * @version 2.0.16
 */

// If uninstall not called from WordPress exit
if( ! defined( 'WP_UNINSTALL_PLUGIN' ) ) {
    exit;
}

function yith_wcwl_uninstall(){
    global $wpdb;

    // define local private attribute
    $wpdb->yith_wcwl_items = $wpdb->prefix . 'yith_wcwl';
    $wpdb->yith_wcwl_wishlists = $wpdb->prefix . 'yith_wcwl_lists';

    // Delete option from options table
    delete_option( 'yith_wcwl_version' );
    delete_option( 'yith_wcwl_db_version' );
    $wpdb->query( $wpdb->prepare( "DELETE FROM {$wpdb->options} WHERE option_name LIKE %s", 'yith_wcwl_%' ) );

    //delete pages created for this plugin
    wp_delete_post( get_option( 'yith-wcwl-pageid' ), true );

    //remove any additional options and custom table
    $sql = "DROP TABLE IF EXISTS <code>&quot; . $wpdb->yith_wcwl_items . &quot;</code>";
    $wpdb->query( $sql );
    $sql = "DROP TABLE IF EXISTS <code>&quot; . $wpdb->yith_wcwl_wishlists . &quot;</code>";
    $wpdb->query( $sql );
}

if ( ! is_multisite() ) {
    yith_wcwl_uninstall();
}
else {
    global $wpdb;
    $blog_ids = $wpdb->get_col( "SELECT blog_id FROM {$wpdb->blogs}" );
    $original_blog_id = get_current_blog_id();

    foreach ( $blog_ids as $blog_id ) {
        switch_to_blog( $blog_id );
        yith_wcwl_uninstall();
    }

    switch_to_blog( $original_blog_id );
}
