Hmm. I am not really sure how to help you. It works on my IOS 5 4s just fine. You may try respringing, and also you can uninstall Status Notifier, I did not nor have I ever used that with this lockscreen and I have never had any issues. Sometimes when I go from locked to unlock the elements needs time to adjust, which is why they suggest downloading 60 second locksreen, so it stays lit longer. But again, I never had any issues. You may try re-downloading it. I got my Weather Elements V4.2.18 from insanelyI repo, section i-themes. Sorry I cant be of more help, I hope this helps. Couple screenshots below to show you where I got my Weather Elements that works fine on my iphone 4s.
