I’m having this problem as well, and nothing I do seems to work:
I’ve received this error as well. I’m using mysql 3.23.58, apache 1.3.33, and php 4.1.

I don’t have connection errors, just dozens of mysql errors, the first of which is:

WordPress database error: [You have an error in your SQL syntax near ‘-inst_categories ( cat_ID int(4) NOT NULL auto_increment, cat_name varchar(5’ at line 1]
CREATE TABLE wp_wp-inst_categories ( cat_ID int(4) NOT NULL auto_increment, cat_name varchar(55) NOT NULL default ”, category_nicename varchar(200) NOT NULL default ”, category_description text NOT NULL, category_parent int(4) NOT NULL default ‘0’, PRIMARY KEY (cat_ID), UNIQUE KEY cat_name (cat_name), KEY category_nicename (category_nicename) )

and the last of which is:

WordPress database error: [You have an error in your SQL syntax near ‘-inst_comments SET comment_type=’pingback’, comment_content = REPLACE(comment_co’ at line 1]
UPDATE wp_wp-inst_comments SET comment_type=’pingback’, comment_content = REPLACE(comment_content, ”, ”) WHERE comment_content LIKE ‘%’

Any tips for me?

Thanks!
