There is currently no formal provision for changing the favicon. However, you can change the file in the root director of Gibbon, just make sure you don’t overwrite it on the next update.
How do I change the favicon in the root director of Gibbon?
Hello again! You can replace the file favicon.ico in Gibbon’s root directory. This will be overwritten on update, unless you specifically don’t upload that file. Thanks, Ross.
What is the folder where the file favicon.ico (in the root directory)? I can not find it
The main Gibbon folder, where index.php is.
