You may receive a security warning or a broken lock icon when viewing an SSL secured page if it's referencing any file from outside the "ssl" subdirectory in your File Manager.

Make sure all of the files associated with your secure web pages, including images and forms, are stored inside the "ssl" subdirectory. If any of these files are stored outside of this directory, visitors to your secure pages will receive a warning that some of the files (usually images) are not in a secure environment.
