 * Hello. Have a problem with upgrading WP version.
    System asks for FTP data and
   after that just informs me – upgrade incomplete (i don’t know how it is exactly
   in english cause i have translated version.) I turned on logging and now i can
   see two extra lines:
 * `Notice: Undefined variable: strings in /data/sites/gomaailm.ee/htdocs/wp-admin/
   includes/class-wp-upgrader.php on line 97`
 * line 97 in that file represents:
    `return new WP_Error('fs_no_folder', sprintf(
   $strings['fs_no_folder'], $dir));`
 * Can someone explain, what could be wrong?
 * When I try to delete some installed plugins from plugin list, i get on header:
 *     ```
       Notice: Undefined variable: title in /data/sites/gomaailm.ee/htdocs/wp-admin/admin-header.php on line 13
   
       Notice: Undefined variable: pagenow in /data/sites/gomaailm.ee/htdocs/wp-admin/admin-header.php on line 49
   
       Notice: Undefined variable: is_iphone in /data/sites/gomaailm.ee/htdocs/wp-admin/admin-header.php on line 66
       ```
