I am having an outside contractor work on my joomla site, and want to protect the users and passwords. I cannot use the solution in this thread since I have too many users - Bulk user delete on joomla 2.5
I have "cloned" the site to a new url, and then used MySQL Workbench to delete all of the users and the user groups map file.
DELETE FROM hhd_users where id>32; DELETE FROM hhd_user_usergroup_map where user_id >32;
However, I now receive a 500 error after trying to login. I cannot use the admin to delete users, even if I can show 1,000 on a screen at once because I have ~20,000 users in the DB.
Is there an easier way to delete the usernames and passwords? Is there another table I should have deleted as well?
