我下載的authimage是1.0版的....

[Fatal error: Call to a member function getId() on a non-object in /home/martylan/public_html/blog/class/dao/blogs.class.php on line 106]

不好意思,我是LT的新手!
剛裝了authimage的外掛,在後台要更新設定時出現了下面的訊息:

"Fatal error: Call to a member function getId() on a non-object in /home/martylan/public_html/blog/class/dao/blogs.class.php on line 106"

我的BLOG:http://martylan.com/blog

我的環境:

Apache version 1.3.39 (Unix)
PHP version 5.2.5
MySQL version 5.0.45-community

謝謝!
