I have tried various solutions to get the iframe to adjust according to the website's content height, so that I can do away with vertical scrollbars, but cannot get a satisfactory solution.
Many solutions ask for a section of code to be added on the 'server side'. If that means I have to edit lines of code within my Wordpress files, where would I do this?
Rather than try to adjust the Facebook page to fit your WordPress install, you're better off changing your WordPress theme to deal with being shown in a Facebook iframe.
When displayed in the iframe, you should have a theme that is fixed-width to your canvas, and no sidebars. Just a content pane. You would then have your regular theme for when visitors arrive outside of a Facebook frame.
The Virtual Theme plugin looks like it could help with this. I've never used it personally.
