title: Magento Manage Categories comes up with grey screen - new install
body: <p>I'm using MAMP Pro to drive the servers so I can develop a Magento site locally. I am new to Magento development and ended up starting over because of several errors I coded. I deleted the previous database out, created a new url in MAMP Pro (i.e devmagento.com:8888) which pointed to a new folder I created, dropped the Magento Community edition in the folder, went through the install process, and everything installed perfectly. Right after installation, I tried going to the Manage Categories page and noticed that it loads part of the header until it gets to "Logged in as bassplayer7". After that there is nothing - just grey. All other admin pages work (I haven't tried every single one, but the ones I've tried have).</p>
  
  <p>Other then reindexing and turning the cache off I did not make ANY changes before going to the categories page. No uploads, no config changes, etc.</p>
  
  <p>In troubleshooting the problem, I turned on logging (in Admin>Config) and the Profiler. The logging seems to only log the front end.</p>
  
  <p>I'm at a bit of a loss as to what to look for. I also went into var/cache, and cleared that.</p>
  
  <p>Any help is appreciated!!</p>
