Fatal error: Call to undefined function base_url() in CodeIgniter


What is Fatal Error

Fatal errors are ones that crash your program and are classified as critical errors. An undefined function or class in the script is the main reason for this type of error.

There are three (3) types of fatal errors:

  • Startup fatal error (when the system can’t run the code at installation)
  • Compile time fatal error (when a programmer tries to use nonexistent data)
  • Runtime fatal error (happens while the program is running, causing the code to stop working completely)
