Oh staff list, it's to do with Habbos imager most likely not allowing them to work without you visiting Habbo.com first, make an imager, it's fairly simple.
For the problem not showing your avatars, go edit the page that has it. [ME.PHP, STAFF.PHP and most likely COMMUNITY.PHP]
Find where it has habbo.com/habbo-imaging/... and check if it has a www. infront of the link and if so remove the '
You must be registered for see links
.'. so instead of
You must be registered for see links
replace with
You must be registered for see links
That will most likely resolve your avatar not showing issue.
With your me.php Having a massive white background within the content, replace the INDEX.PHP in your wwwroot or htdocs folder with the one provided where you downloaded theme. [Its not the one in your theme, but the one in either wwwroot or htdocs.]
