  • Hi Ghulam,

    It looks like your vendor folder may either be missing or not readable by the server. It is located in the root of your Gibbon install, and should have file permissions for the system to access it (often 0755 for folders and 0644 for files).
  • I just checked the root . Vendor folder is missing. So now need further assistance.

  • Hi Ghulam,

    If you access the same version you are using from our GitHub repo, then you can download it, unzip it, and upload the /vendor file to your server.


  • Respected Sandra,

    Thanks for the quick worked.
