Pages not available After Security Measures

I have tried to secure my wordpress install by locking down the root .htacess file with the following security measures:

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

# END WordPress

# SECURE WP-CONFIG.PHP
<Files wp\-config\.php>
Order Deny,Allow
Deny from all
Allow from 121.217.101.201
</Files>

# PROTECT SENSITIVE FILES BY FILE TYPE
<FilesMatch "\.(htaccess|htpasswd|ini|php|fla|psd|log)$">
Order Deny,Allow
Deny from all
Allow from 121.217.101.201
</FilesMatch>

And also locked down the wp-admin directory with the following within .htaccess file in the wp-admin directory:

# SECURE WP-ADMIN FILES
<FilesMatch "*.*">
Order Deny,Allow
Deny from all
Allow from 121.217.101.201
</FilesMatch>

# PROTECT WP-LOGIN.PHP
<Files wp\-login\.php>
Order Deny,Allow
Deny from all
Allow from 121.217.101.201
</Files>

Also removed the install.php file – was following a tutorial.

I have tried logging in to site and cant seem to now. It is located within a secondary folder on server and I just get a 404 error message from the initial install of WP in root.

I removed the .htacess file from wp-admin and also reverted root .htacess but it still doesnt work. Any advice on how I can view files once agin would be great as I have just about finished project.
