Problem #

You see the following Oops! error:

main(): Failed opening required '/path/to/whmcs/..filename.php'...

Cause #

A required file is missing (in this example, /whmcs/includes/orderfunctions.php).

Solution #

Upload the missing file to the folder path in the error message.

• We recommend reuploading of all the WHMCS files to ensure that no other files are missing.
• Make certain that you successfully overwrite all of WHMCS’s files.
