there is message like
Mod Rewrite Rules
Mod Rewrite rules cannot be updated!
You must have BEGIN and END markers in /myserverlocation/html/pilates/.htaccess for the auto update to work. They look like this and surround the main WordPress mod_rewrite rules:
# BEGIN WordPress
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
# END WordPress
Refresh this page when you have updated your .htaccess file.
this example confuses! because "main wordpress rules" are more now.
and please write some explanation like: surround main rules after
RewriteEngine On
RewriteBase /
also clear please, that if there are additional custom rules, user should know, understand what he is doing, whether to surround them also...
