Error loading language on Code Igniter Rest Server

I had the same issue and solved it.

The problem is that codeigniter can't find the rest_controller translations. You just need to create this file /application/languages/english/rest_controller_lang.php

Then copy & paste this code inside:

<?php/* * English language */$lang['text_rest_invalid_api_key'] = 'Invalid API key %s'; // %s is the REST API key$lang['text_rest_invalid_credentials'] = 'Invalid credentials';$lang['text_rest_ip_denied'] = 'IP denied';$lang['text_rest_ip_unauthorized'] = 'IP unauthorized';$lang['text_rest_unauthorized'] = 'Unauthorized';$lang['text_rest_ajax_only'] = 'Only AJAX requests are allowed';$lang['text_rest_api_key_unauthorized'] = 'This API key does not have access to the requested controller';$lang['text_rest_api_key_permissions'] = 'This API key does not have enough permissions';$lang['text_rest_api_key_time_limit'] = 'This API key has reached the time limit for this method';$lang['text_rest_ip_address_time_limit'] = 'This IP Address has reached the time limit for this method';$lang['text_rest_unknown_method'] = 'Unknown method';$lang['text_rest_unsupported'] = 'Unsupported protocol';

The original repository:https://github.com/chriskacerguis/codeigniter-restserver/blob/master/application/language/english/rest_controller_lang.php

if you are using linux server you can directly get it using wget command and row view of git like this,

wget https://raw.githubusercontent.com/chriskacerguis/codeigniter-restserver/master/application/language/english/rest_controller_lang.php

Hope it helps
