Troubleshooting a File Not Found Error
From WHMCS Documentation
If you experience a File not found error, this may mean that a file is not present or is not accessible at the expected location. Performing the steps below will help you resolve this issue.
Checking for the File
To troubleshoot this, begin by validating whether the file is present in the local storage.
To do this:
- Check whether the file exists.
- Check the file's permissions and make certain that they allow access to the web user. For AWS S3, use AWS (or your compatible storage provider's) console to verify that the file is stored with the indicated key.
Test Configuration
You can confirm storage location accessibility using the Test Configuration feature.
To do this:
- Go to the Configurations tab at Configuration () > System Settings > Storage Settings or, prior to WHMCS 8.0, Setup > Storage Settings.
- Select the configuration you want to test.
- Click Test.
For AWS S3 (or compatible providers) this should also indicate whether there are any issues with the provided access key or access secret.
