Vincent Paul on "Homepage Stuck, Please help!"

My homepage won't update and it's stuck on the date of 2013-06-23 19:49:59 If someone can please help me fix this homepage not changing issue I would greatly appreciate it.

Here's the code for my .htaccess currently. I've troubleshooted all of the regular things that people have suggested such as deactiviting plugins, refreshing browser cache but nothing has been able to fix it.

# BEGIN WPSuperCache
# END WPSuperCache

# BEGIN s2Member GZIP exclusions
<IfModule mod_rewrite.c>
	RewriteEngine On
	RewriteBase /
	RewriteCond %{QUERY_STRING} (^|\?|&)s2member_file_download\=.+ [OR]
	RewriteCond %{QUERY_STRING} (^|\?|&)no-gzip\=1
	RewriteRule .* - [E=no-gzip:1]
</IfModule>
# END s2Member GZIP exclusions

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

# END WordPress
