Operation corrupted

Hello, no, on the contrary. Column “tag” should be in database table!

Hi, there are several ways we can do this:
– if you don’t have a lot of keywords in table you can totally reinstall plugin;
– if you have access to cpanel of your hosting you can mannualy add column ‘tag’ (tag VARCHAR(20) NOT NULL) to table ‘[your_wp_prefix]_internalinks’ through the phpmyadmin;
– or:

1. put this code to file functions.php

add_action('init', 'ilgen_insert_column');
function ilgen_insert_column(){
    if(is_admin() && 'internal_links_generator' == $_GET['page']){
        global $wpdb;
        if(!$wpdb->query("SHOW COLUMNS FROM {$wpdb->prefix}internalinks LIKE 'tag'")){
            if($wpdb->query("ALTER TABLE {$wpdb->prefix}internalinks ADD tag VARCHAR(20) CHARACTER SET utf8 NOT NULL")){
                echo '<script>alert("Internal links: column \'tag\' successfully added!");</script>';
            }
        }
    }
}

2. open once plugin page http://[your_domain.com]/wp-admin/options-general.php?page=internal_links_generator
3. when you saw window with text “Internal links: column ‘tag’ successfully added!” remove code from file functions.php

… and don’t forget to disable/enable plugin after update.
