Following Dr. Bytes recommendation, I am trying to upgrade from 1.5.0 to 1.5.4. I have a lot of residual files and just want to do a clean install. I have a relatively simple site, so I am ok with the work of starting from scratch.

I set up a new folder on my site with a test name. I downloaded all of the newest 1.5.4 files, set up my database on my hosting account and went through the install procedure. Everything went smooth.

Result: I can access the new site, but when I try to access the admin panel, I just get a white screen.

I went through all of the FAQ suggestions (clear cache, etc.) to no avail. I have not yet renamed my admin file, so it is not that. I looked for the configure.php files in the "root" directory in the subdirectory, but there is nothing there. Is it not possible to install it in a subdirectory as a test until I can get everything configured?
