我目前正在开发一个简单的插件。激活我的插件工作正常。然而，只要我的插件处于活动状态，我就不能激活任何其他插件。此外，编辑链接也不起作用。

这方面的任何帮助都将是巨大的！下面是主插件文件sponsoren的代码。php

<?php  
/* 
Plugin Name: Sponsoren
Plugin URI:

// Enqueue Scripts
add_action( \'admin_enqueue_scripts\', \'sponsoren_admin\' );
add_action(\'admin_menu\', \'sponsoren_custom_menu_page\');
add_action( \'wp_enqueue_scripts\', \'sponsoren_frontend\' );

function sponsoren_custom_menu_page() {
   $page = add_menu_page( \'Sponsoren\', \'Sponsoren\', \'manage_options\', 
       \'sponsoren/sponsoren-admin.php\', \'\', plugins_url( \'sponsoren/images/icon.png\' ), 33 );
}

function sponsoren_admin() {
    wp_enqueue_style( \'sponsoren-admin-style\', plugins_url(\'/stylesheet.css\', __FILE__) );
    wp_enqueue_script( \'sponsoren-admin-script\', plugins_url(\'/script.js\', __FILE__) );
}

function sponsoren_frontend() {
    wp_enqueue_style( \'sponsoren-frontend-style\', plugins_url(\'/sponsoren.css\', __FILE__) );
    wp_enqueue_script( \'sponsoren-frontend-script\', plugins_url(\'/sponsoren.js\', __FILE__), array( \'jquery\' ) );
}

// Create database table upon activation
function jal_install() {
   global $wpdb;

   $table_name = $wpdb->prefix . "sponsoren";

   $sql = "CREATE TABLE $table_name (
   id int NOT NULL AUTO_INCREMENT,
   name tinytext,
   bild tinytext,
   url tinytext,
   PRIMARY KEY id (id)
    );";

}

register_activation_hook( __FILE__, \'jal_install\' );

// Ajax action used in sponsoren-admin.php
add_action(\'wp_ajax_sponsor_delete\', \'sponsor_del\');
function sponsor_del() {
    global $wpdb;
    $wpdb->delete( $wpdb->prefix.\'sponsoren\', array( \'id\' => $_POST[\'deleteid\'] ) );
    die();
}

// Widget
function widget_sponsoren_frontend($args=array(), $params=array()) {

    $title = get_option(\'widget_sponsoren_title\');

    echo $before_widget;
    echo $before_title . $title . $after_title;
    // some more widget output

    echo $after_widget; 
}

wp_register_sidebar_widget(\'widget_sponsoren\',\'Unsere Sponsoren\', \'widget_sponsoren_frontend\');

// Widget Options
wp_register_widget_control(
    \'widget_sponsoren\',     // id
    \'widget_sponsoren\',     // name
    \'widget_sponsoren_control\'  // callback function
);

function widget_sponsoren_control($args=array(), $params=array()) {

    if (isset($_POST[\'submitted\'])) {
        update_option(\'widget_sponsoren_title\', $_POST[\'widgettitle\']);
    }

    $widgettitle = get_option(\'widget_sponsoren_title\');
    ?>

    Widget Title:<br />
    <input type="text" class="widefat" name="widgettitle" value="<?php echo stripslashes($widgettitle); ?>" />

    <input type="hidden" name="submitted" value="0" />
