  1. Hi.
    I install the plugin on the site (WordPress) for registration in Russian(Allow Cyrillic Usernames) and now I need to change in the sql database, in the table wp_users, in the column user_nicename permission to write more characters from by default 50 to 255.
    How to do this?
    Tried, did not work:
    ALTER TABLE wp_users ALTER COLUMN user_nicename varchar(200) NOT NULL -error

    ALTER TABLE `wp_users` CHANGE `user_nicename` `user_nicename` VARCHAR(255) NOT NULL DEFAULT ”; -error #1067
    Found in net tip:
    show variables like ‘sql_mode’ ;
    And remove the sql_mode “NO_ZERO_IN_DATE,NO_ZERO_DATE” to make it work.
    How to do this one?
