I could really use some expert advice.
I have a Home Page Component that only includes a VF page.
I defined it as a custom component with (HTML area).
This is my code:
<br><iframe src="/apex/SubscriberCard?core.apexpages.devmode.url=1" width="100%"" height="100%"></iframe><br>
I can see the page when I'm in the component Edit mode.
But when I go to the Homepage I see nothing but an horizontal line at the top.
I can't figure out what is wrong and why it is not working.
