The lastest version of bowob plugin 5.7 (like facebook footerchat) is not compatible with wp 3.0.1 but y resolved the bug changing a few lines in the bowob plugin code.
First go to http://bowob.com and download the plugin for wordpress, install and open the editor page for bowob plugin, Open /bowob.php
change this line:
wp_redirect($bowob_blogurl . “/index.php”);
Three lines after. change this line:
wp_redirect($bowob_blogurl . “/wp-login.php?redirect_to=” . (($bowob_pageperma) ? “bowob” : “?page_id=” . $bowob_pageid));
I have the same problem as bowob it is not working and I made this changes but now I am taking the message that plugin cant activate because of a problem : Parse error: syntax error, unexpected ‘;’ in /home2/lifeisw1/public_html/wp-content/plugins/bowob.php on line 112
