Please bid only if you are proficient with WHMCS,
In "Setup" > "General Settings" when I click "Save", this error comes up:
You don't have permission to access /members/admin/[url removed, login to view] on this server.
Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request."
This is a minor fix as everything else is working properly. I have recently updated my WHMCS to 5.0.3 and after that I am receiving this error.
