I just visited your site. I tried the Add Category option and got the blank frame. I clicked in the frame and told the browser to show me the source code. Here is what it displayed:
Code:
<html>
<head>
<title>Category Database: Add a New Category.</title>
</head>
<body bgcolor="#DDDDDD">
<form action="http://wilson33.hypermart.net/link/cgi-bin/admin/admin.cgi" method="POST">
<input type=hidden name="db" value="category">
<table border=1 bgcolor="#FFFFFF" cellpadding=5 cellspacing=3 width=500 valign=top>
<tr><td colspan=2 bgcolor="navy">
<FONT FACE="MS Sans Serif, arial,helvetica" size=1 COLOR="#FFFFFF">
<b>Category Database: Add a New Category</b>
</td></tr>
<tr><td>
<p><center><font face="verdana,arial,helvetica" size="4"><b>
Add a New Category
</b></font></center><br>
<font face="verdana,arial,helvetica" size="2">

According to this, you are missing the categoryid.txt file. Create it in the admin/data directory and chmod it to 666. That should solve your problem.
As a general rule of thumb, always look at the source code when you get a blank screen or frame to see if there is anything in it.
I hope this helps.
