 * Immediately after activating the plugin and trying to access the “login” page
   I have the following severe error:
 * MySQL Connection Failed: SQLSTATE[HY000] [1130] Host ‘127.0.0.1’ is not allowed
   to connect to this MariaDB server
 * Any ideas ?
 * Thanks !

 * Hi,
 * You are using MariaDB server instead of MySQL. Did you run mysql_upgrade to finish
   the upgrade? This is needed to ensure that your mysql privilege and event tables
   are updated with the new fields MariaDB uses.
 * The plugin is designed and tested for default MySQL only.
 * But You can try with this
    GRANT ALL ON *.* to root@’127.0.0.1′ IDENTIFIED BY‘
   root_password’; FLUSH PRIVILEGES;
 * If you still have issues, you can get a file based version of the plugin from
   support[at]genialsouls[dot]com which don’t use db connection for login.
 * Regards

 * Hi,
    all WordPress updates I did from the “Updates” page were “automatic/full”…
   so I actually think that, yes, I did run mysql_upgrade… and I am not sure I can
   ask my provider to run the grant/flush commands you are suggesting…
 * Did I miss something else ?
 * I will try to write to support[at]genialsouls[dot]com to have the “file based”
   version…
 * Thanks again !
