fatal error uncaught error call to undefined 18.04
The error message "Fatal error: Uncaught Error: Call to undefined..." typically occurs in PHP when you are trying to call a function that is not defined or does not exist. Since the error message you provided does not specify the function name, I'll give you some general steps to troubleshoot this type of error:

Check the Error Message: Make sure to carefully read the entire error message. The error message should provide you with the file name and line number where the error occurred. It may also indicate the name of the undefined function.

Verify Function Existence: Double-check that the function you are trying to call actually exists and is defined in your code or in a required file. If it is a built-in PHP function, confirm that it is available in your PHP version.

Namespace Issues: If you are using namespaces in your PHP code, ensure that you are correctly referencing the function with the correct namespace, especially if the function is from a different namespace or a different class.

Autoloading: If you are using autoloading to load classes and functions, verify that the autoloader is set up correctly and can locate the required function's definition.

Include or Require: If the function is defined in another file, make sure you have included or required that file before calling the function.

Check Function Name Spelling: Double-check the spelling of the function name to ensure there are no typos or misspellings.

PHP Version Compatibility: Some functions might not be available in older PHP versions. Check the PHP documentation to ensure the function is supported in your PHP version.

PHP Extension: If the function is provided by a PHP extension, make sure the extension is enabled in your PHP configuration.

Error Reporting: If error reporting is disabled or set to a low level, you might not see the full error message. Ensure that error reporting is enabled to see detailed error messages.

Debugging: Use debugging techniques, such as var_dump(), print_r(), or echo statements, to inspect variables and trace the flow of your code to identify where the error is occurring.

By following these steps, you should be able to identify the specific cause of the "Fatal error: Uncaught Error: Call to undefined..." issue in your PHP code and then proceed to fix it accordingly.
