How can the error message "File is writeable by group" be resolved when using KCFinder with PHP?

The error message "File is writeable by group" indicates that the file or directory being accessed by KCFinder is writable by a group, which can pose a security risk. To resolve this issue, you can change the file permissions to ensure that it is not writable by a group. This can be done by using the chmod function in PHP to set the appropriate permissions for the file or directory.

// Set the file permissions to ensure it is not writable by a group
chmod('/path/to/your/file/or/directory', 0644);
