Shouldn't <div style='height:700px'> actually be <div style='height:100%'>? If so how can I edit this so posts can be replied to? The only way so far I've been able to see all the reply options is if I click "change appearance" because it will let me scroll in the embedded window.
You have hopelessly corrupted your code in the last couple of hours.
Earlier I was able to register and login and display the one post (in the truncated form you complain about). Now the forum just produces errors at every link.
Return it to the state it was in and I may be able to assist.
which you suggest is part of the problem is NOT. Every forum has this line which is designed to be just tall enough to display the "Loading" graphic . It will not affect the height of the forum page that then loads. To demonstrate that just check out a couple of my embedded forums with https implemented to confirm it.
