So years later, I also download Community Edition (which promises to let me get a full PHP stack running "in a few minutes").
I am having the same problem, cannot login to MySQL with phpMyAdmin, error #1045 Cannot log in to the MySQL server
I have tried all combinations of admin, root, zend, and null pw or pw = '1234' or pw='zend'
I have tried logging into MySQL from the command line ('mysql -u root ) but same thing.
I have searched forums here and on Stack Overflow.
Lots of people asking the same question. Nobody answering. Actually, the people who are successful are those who have uninstalled Zend and installed WAMP or XAMP.
This is ridiculous.
