noticed installation problems

Try creating a table ‘wp_linkclicks’.
I guess this is created by a plugin because I don’t have that table.

This table is used by OZH’s click counter plugin.

For some reason, your table definition is incorrect. Use PHPMyAdmin and drop (i.e. remove) the wp_linkclicks table.

You should then recreate it via the following piece of SQL:
CREATE TABLE wp_linkclicks (
link_id INT NOT NULL AUTO_INCREMENT ,
link_url TEXT NOT NULL ,
link_clicks INT NOT NULL ,
link_date DATETIME NOT NULL ,
link_title TEXT NOT NULL ,
UNIQUE (
link_id
)
);

“what about the source for go.php someone?”

Have you tried clicking the link I gave you?

go.php is part of the click counter plugin developed by OZH and is not a core part of WP.

The source code, usage and installation instructions can all be found on OZH’s plugin page.
