CI in a Linux environment setup

I had big problems with the source because I think it is has been converted to Spanish.

Anyway some good news, I downloaded the source and made some changes:
1. modified application/config/config.php
2. modified application/config/routes.php
3. added application/controllers/Welcome.php
4. added application/views/welcome_message.php
5. download, unzip and add and/or replace the current files
6. calling index.php should open the view welcome_message.php file

// DEBUG - enable logging
1. make sure the index.php ENVIRONMENT is set to 'development'
2. modify application/config.php and change these two lines:
a. $config['log_threshold'] = 'development'===ENVIRONMENT ? 4 : 1;
b. $config['log_file_permissions'] = 'development'===ENVIRONMENT ? 0777 : 0644;

Check the error application/logs/log-2019-10-29.php which can be deleted after fixing the bugs.

I know your problem has not been solved but at least you will be able to gradually load the changes in your application and check the error log

The changes may be downloaded here:

Let me know when you have downloaded the above file so that I can delete it.
