Some others have reported long secs of seeing a white page and a slow appearance of the forum colors and frames.

Could this be the problem; found in the source:
Code
 <style type="text/css">
.popup_menu a,
.popup_menu label { display: block; padding: 2px; cursor: pointer; }
.ubbcode-pre {
	font-family: monospace;
	white-space: pre;
}
pre {
margin: 0px;
}
</style>
