install directory /wordpress/
but site address set to /blog/

they are ok for both /wordpress/

then got problem.

I install in sub-folder

when I change it , then go to super cache config , it will show

“Rewrite rules must be updated
The rewrite rules required by this plugin have changed or are missing. Scroll down the Advanced Settings page and click the Update Mod_Rewrite Rules button.”

but scroll down the advance setting, their do not have update mod_rewrite rules button. only show :

Mod Rewrite rules cannot be updated!
You must have BEGIN and END markers in /.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 WordPressRefresh this page when you have updated your .htaccess file.

and it can’t be generated, always 0 page regenerated.

but I change the site homepage url back same as install folder, everything are ok.
