Error 503. Service Unavailable Installation Error

Any ideas on why I'm having this error. Any other app installs just fine


  • Hi Kay, welcome to the forums. I've removed your duplicate post, please do try to only post one thread per question, as duplicates can slow down our ability to respond to questions and make it harder for people to search for answers in the future.

    Error 503 is a server-side error, it sounds like something is missing in the configuration side, rather than in Gibbon itself. In this case, if you're using Softaculous to install, the best bet would be to get in touch with the Softaculous support people, as it may be something on their side. We are happy that they support Gibbon in their installer, but we don't have any control over their system or how their installer works, so our ability to assist here is limited.
