I was upgrading a 1.5.1 install to 1.5.4
Imported the DB
Did the DB upgrade fine

Store page displays this text at the bottom

WARNING: An Error occurred, please refresh the page and try again.

Trying to access the admin area I get this

WARNING: An Error occurred, please refresh the page and try again.

The resulting debug file contents are

In a normal configuration, the admin_activity_log table has its primary key set to be the log_id field, which is an auto-incrementing integer field.
It seems yours is not properly set to be auto-incrementing, for whatever reason.

DrByte,
Thank You
I ran this and can now access

ALTER TABLE admin_activity_log CHANGE COLUMN   log_id  log_id int(15) NOT NULL auto_increment;

My bad. I should have said big-integer field.

The upgrade SQL (since v150) is:

ALTER TABLE admin_activity_log CHANGE COLUMN log_id log_id bigint(15) NOT NULL auto_increment;
