BuddyPress.org

I am using the WordPress theme Tropical Dream and have installed BuddyPress, together with the Template Pack. As per the Stage 3 instructions I then checked out the “My Account” links, but found that they weren’t appearing correctly (although the pre-existing WordPress pages were): the (left-hand) sidebar was missing, with the BuddyPress content filling the page and pasted directly on to the background instead of in a containing box as happens with the non-BuddyPress pages. (Also, the BuddyPress admin bar was right at the very top of the page background, rather than merely above the header area.) I checked the structure of the page.php file (see http://pastebin.com/kvWPdga9), as per the instructions, and tried to make appropriate adaptations to the 11 BuddyPress files, but regardless of ANY changes I made to these files’ HTML structure the corresponding pages still appeared exactly the same. I thought this might be a cache problem, but clearing it made no difference whatsoever. I’m not a complete newbie, but neither am I proficient in php, so I’m rather stuck, now. Can you help, please? Exactly what changes do I need to make, and to which files? I know that you’ve been able to assist others with similar problems, so I’m hoping that you might be able to clear up this mystery for me, too.
