Hi John!
I do not see the Supersized code on the page you provided — have you deactivated the plugin? I have used WP Supersized with Fuji multiple times and there seems to be no problems with the plugin compatibility. If the issue is still topical, could you please send me the admin login and password to support@satoristudio.net (no disclosure guaranteed) — this way I will be able to troubleshoot and fix the problem quicker and more efficiently.
Sincerely,
Andrew | Satori
