Codeigniter 4 shows an error when I run the CI4 application, Ho

Answer 1

Assume that your root folder of your CI4 project is rootproject. Edit rootproject/.env file. On line 17 change from:

#  CI_ENVIRONMENT = production

to:

CI_ENVIRONMENT = development

Save it.

Refresh your browser that pointing to your CI4 project. It should give you many error messages.

If there is something written as CacheException, than your cache folders are not writable. Make it writable;

Ubuntu:

chown -Rv www-data rootproject/writable

CentOS:

chown -Rv apache rootproject/writable

Easy way:

chmod 777 -Rv rootproject/writable
