Problem
The following error appears when you click Test Connection at Configuration () > System Settings > Database Backups:
(S)FTP: Unable to write to temp file
Cause
This error indicates that WHMCS cannot write to a test file in the PHP system directory (the sys_temp_dir
PHP setting) via the PHP fwrite
function.
Solution
Make certain that:
- The PHP system temporary directory has writeable permissions.
- The
fwrite
function is not disabled in the PHP configuration.
