CiviCRM >> Administer CiviCRM >> Profiles is blank
That's a headscratcher for sure.  Here are some things to try:


Review the log at ConfigAndLog just after you load the Profiles page.
I've seen this happen when your Resource URLs and directories aren't set properly.  Check both: Administer » System Settings » Resource URLS and Administer » System Settings » Directories.
Check the HTML to see which div is missing compared to the demo site.  Knowing that will help someone who wants to look in the source code.
You said you cleared caches - I assume that include removing templates_c.  If not, please delete that. Also check the permissions on templates_c to make sure this isn't a permission error on the compiled template.
