[Plugin: WP-OpenID] sql and js errors

Plugin version: 2.1.8
Sorry i’m not really familiar with php, js and css. Just a wordpress user.

After trying 2 other OpenID plugins, this one seems to work somehow, but not really well. After activation, there’s an error on all pages:
Line:44
Char:3
Code:0
Error:”getElementById” – is null or not an object
It dissapears when i turn the plugin off. It doesn’t seem to break anything though.

When somebody posts a comments under their openid, it produces the following error:WordPress database error: [You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ‘SET openid=’1′ WHERE comment_ID=’41’ LIMIT 1′ at line 1]
UPDATE SET openid=’1′ WHERE comment_ID=’41’ LIMIT 1

Warning: Cannot modify header information – headers already sent by (output started at /home/campus/blog.campus-shop.ru/docs/wps/wp-includes/wp-db.php:133) in /home/campus/blog.campus-shop.ru/docs/wps/wp-includes/pluggable.php on line 331

But it still posts the comment.

After that if you want to post a second comment, there’s also a second problem – it remembers you, but as your identity, instead of writing your openid, it just writes the openid url.

Also, when you just want to login using your openID, it brings you to the admin panel, is that supposed to be so? I thought it should bring you to the main page.
