So playing an upgrade now - apparently you cannot upgrade to 4.5.5 just by using the patch.sql anymore. So using older version and got it to 4.5.0. With previous upgrade you can just apply the sql patch to 4.5.x and then run the install, set the db and provide blowfish key... Seems like this is not the case anymore. The sql patch 4.5.0->4.5.5 takes the db to 4.5.4 only. There is patch_post.php that further changes the db and config.php. Using that manually upgrade db with already installed 4.5.5 does not allow me to login to admin even after changing all new security variables and constants in config.php Also an email send form the system to activate suspended admin account takes me to customer side of the cart....
I don't know to cry or to smile

Ok so I will install 4.5.0 and run the upgrade from within....
