.htaccess issues with CI3 inside Wordpress directory

Here is mine hope it will works with you.

My primary base folder for example is public_html and can access through http://localhost
and I have CI project openspire that can be access through http://localhost/openspire/

And here is my .htaccess

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

There are those who tell lies with meaning behind them and those meaning less lies!
