Hello Gibbon group, i install Gibbon in my subdomain, it can run.
but the Logo and function’s button become the error icon.
is any thing i can do, and fix it?
Hi Kevin,
Be sure to check the Base URL at the top of the System Settings, it needs to match the full and valid URL for your Gibbon installation. Assets not loading is a common sign that this URL may be incorrect. Hope this helps!
Thank you Sandra, i check the System Setting’s URL , is match the URL where Gibbon installation.
When i try to copy the picture’s link and open to new window, it shows 403 error.
but i check all the folder’s permissions, the setting is same like my main installation
If you need more information.please tell me, thank you.
Kevin
It sounds like it may be the file permissions rather than just the folder permissions. If you’re changing permissions with a command like chmod, be sure to use the -R flag to recursively update all the files as well.
