RewriteBase Error After Every Single Update

I want to report an error that is occurring after every single update of the s2member plugin.

Before the update, my RewriteBase shows this:

# BEGIN s2Member GZIP exclusions

	RewriteEngine On
	RewriteBase /usbgforg/
	RewriteCond %{QUERY_STRING} (^|?|&)s2member_file_download=.+
	RewriteRule .* - [E=no-gzip:1]

# END s2Member GZIP exclusions

After the update, I experience a 500 error and my RewriteBase shows this:

# BEGIN s2Member GZIP exclusions

	RewriteEngine On
	RewriteBase usbgforg_wordpress
	RewriteCond %{QUERY_STRING} (^|?|&)s2member_file_download=.+
	RewriteRule .* - [E=no-gzip:1]

# END s2Member GZIP exclusions

The RewriteBase is being rewritten and the name of the database is being substituted.

Thank you in advance for any assistance.
