Database User + Post

Nope the guest is still there:

INSERT INTO users (id, group_id, username, password, email, title, realname, url, jabber, icq, msn, aim, yahoo, location, use_avatar, signature, disp_topics, disp_posts, email_setting, save_pass, notify_with_post, show_smilies, show_img, show_img_sig, show_avatars, show_sig, timezone, language, style, num_posts, last_post, registered, registration_ip, last_visit, admin_note, activate_string, activate_key, num_posts_chatbox, last_post_chatbox, rep_minus, rep_plus, reputation_enable, reputation_enable_adm) VALUES('1', '3', 'Guest', 'Guest', 'Guest', NULL, NULL, NULL, NULL, NULL, NULL, NULL, NULL, NULL, '0', NULL, NULL, NULL, '1', '1', '0', '1', '1', '1', '1', '1', '0', 'English', 'Oxygen', '0', NULL, '0', '0.0.0.0', '0', NULL, NULL, NULL, '0', NULL, '0', '0', '1194272699', '1', '1');

I've deleted the new guest database for the old one thats all I did. In the actual database, I didn't touch anything but I'll go check. What do I have to find and what do I have to do. I really suck with manging database. I'm here cause I want to learn.

Okay I'm so lost, can you give me an example?

Right. That error means you deleted the guest user from your users table. Don't do that
That's all I'm saying

Run that insert query you showed me earlier in the topic
