i just download invoiceplane v 1.4.10 then upload to my server and install but error cannot access to installation page.
solution just edit application/config/config.php
$config[‘base_url’] = IP_URL;
change to your full url
$config[‘base_url’] = ‘http://demo.narkdeveloper.net/invoice’;
now you can access installation page, after install success try to enable .htaccess later.
