Volunteer plugin

[olmy]

Thanks for testing - what theme are you using? plugins?

I installed the plugin and it works except after login I get:

Warning: Cannot modify header information - headers already sent by (output started at /home/user/public_html/site/theme/template/template.php:15) in /home/user/public_html/site/plugins/volunteer.php on line 245

Fatal error: Call to a member function query() on a non-object in /home/user/public_html/site/plugins/volunteer.php on line 381

If I refresh my login/profile page showing the above error, it then displays fine. Further visit/refreshes to the profile page (while logged in) also work fine.

If I log-out (disconnect), I get this error:

Warning: Cannot modify header information - headers already sent by (output started at /home/user/public_html/site/theme/template/template.php:15) in /home/user/public_html/site/plugins/volunteer.php on line 172

As before, if I refresh the page, there's no error. So the errors occur on page build after login or logout.

Any thoughts please?
