Hoping someone can help with this. I have a youtube video on the front page of a wordpress blog and when i have an opt-in lightbox popup, the youtube video overlaps part of the lightbox. I also have the same problem with a drop down menu that drops down behind the youtube video. How do I fix this? I've tried the mode=transparent and it didn't work. Any help would be appreciated as this has been driving me crazy for 2 weeks.
It sounds like some sort of sizing issue. I cannot determine anything without some code though. Also which lightbox script are you using? There are a few out there and each will probably have a separate solution to this type of issue. If anything check the sizes of the lightbox elements.
