# PLugin won’t activate

 * Hi
 * I’ve recently updated to WordPress 5.5 and needed to deactivate WP_Postratings
   to troubleshoot a problem which was resolved. I then upgraded to version 1.89
   from 1.88 and the plugin will not activate due to a fatal error.
 * I seem to remember that when I installed 1.88 that I remarked out an alter table
   command
    // maybe_add_column($wpdb->ratings, ‘rating_userid’, “ALTER TABLE $wpdb-
   >ratings ADD rating_userid INT( 10 ) NOT NULL DEFAULT ‘0’;”);
 * I tried this again but still get an error

 * I have gone into phpmyadmin and the table wp_ratings has been created as have
   the indexes so I am at a loss as to what the error is
 * Any help appreciated

 * I have since restored to the previous version of wordpress and re-updated to 
   1.89 and now I get this error when trying to network activate the plugin
 * Fatal error: Cannot redeclare postratings_init() (previously declared in /nas/

 * Apologies I see this error is because the plugin is already activated under the
   site plugins list.
 * I think the issue here may have been due to the upgrade to wp v 5.5 and resolved
   through the rollback.
 * Please ignore this support request and apologies for any inconvenience caused
