A blank page usually means a fatal PHP error.
Have you reviewed this FAQ? When I click some button or follow some link, I'm left with a blank page. What do I do?
Details on the error should be available in the error log.
There is a special case where a blank page appears at install time but no helpful error appears in the log. I’ve seen this if php’s mysql libraries are not installed. For a brand new server, you will want to confirm this prerequisite as well.
