Upgrade b2 to WordPress — Login Problem

I was helping my friend upgrade his blog from b2 to wordpress 1.5. The upgrade worked except it wouldn’t allow either one of us to log in. Then I remembered this same problem when I tried to upgrade one of my blogs a while ago.

This was the problem. Since all of b2′s configurations were in the file b2config.php, and all of WordPress’ configurations were stored in the database, some data had to be manually imported over.

To fix the login problem, go into phpmyAdmin and find the ‘options’ table in your blog database. Look for the option name “siteurl” and make sure it’s option_value is your website. Fresh upgrades won’t have a value here, therefore, you wouldn’t be able to log into your WordPress. Just something to keep in mind when upgrading b2 to worpdress!
