Joomla! 3.2 registration and login problem (workaround)
Another important problem is associated with new Joomla! passwords. Joomla! 3.2 supports 128-bit passwords (you can enable Strong Passwords in User – Joomla! plugin configuration) and when the old ones are shorter and less secure you may notice the problem with login after user registration. When you upgrade your older Joomla! version and keep this option disable, then everything should be working fine – all passwords will be saved in the database in an old format. In other case, you will get mix of old and new passwords which means that new registered users can’t login (password reset is broken also). To fix this issue you need to modify several Joomla! core files but just particular lines. Solution for this problem is provided by Alterbrains and may be found here Joomla 3.2 passwords issue (solution)Blank screen after Joomla! 3.2 upgrade
Last but not least is the problem with blank screen after upgrading. This problem may be related with other things. First of all, you should compare Joomla! requirements with your server settings and make sure that all your extensions are compatible with Joomla! 3.2. While Joomla! 3.2 recommends to do set displaying errors option in PHP to off the blank screen, it tells you absolutely nothing. The important part is to see the error description. Solution for that is in this article and it describes how to enable showing errors on frontpage. Please remember to disable this function when you resolve your problem!Quickstart Installation Database Import Problem

PHP Warning (Strict) messages on the frontpage
Exactly like in the previous case, the problem is related to the server configuration. While Joomla! recommends to display_errors to OFF, many hosting companies enable this option by default. Solution for this problem may be found here: Quickstart Installation Problems – How to fix them? When disabling this option via ini_set() rule is not working, it means that global server configuration should be changed. In this case, the only way to solve this problem is to contact with your hosting company.More
