Error with WordPress Hit Counter

Hello, I’m a newbie and I’m having trouble with WordPress Hit Counter. I’ve not been able to find this error anywhere on here, so I hope someone can help me figure this out.

I’ve installed WordPress Hit Counter v2.6 and I’m running WordPress 3.1.3. When I go to change the settings for the Hit Counter and press save, I get these two errors:

Warning: join() [function.join]: Invalid arguments passed in /home/content/n/t/r/ntrost/html/thaiwoman/wp-content/plugins/wordpress-hit-counter/hitcounter_menu.php on line 49

Warning: Cannot modify header information – headers already sent by (output started at /home/content/n/t/r/ntrost/html/thaiwoman/wp-content/plugins/wordpress-hit-counter/hitcounter_menu.php:49) in /home/content/n/t/r/ntrost/html/thaiwoman/wp-includes/pluggable.php on line 897

The line that hitcounter_menu.php:49 refers to has to do with excluding an ip address. When I enter an ip address to exclued, it seems to update fine, but what if I don’t want to exclude an ip? Is the generation of this error supposed to come up in Hit Counter, or is Hit Counter not working correctly? If it’s not working correctly, how do I get it to work correctly?

Also as a note, I’m developing this wordpress site on a free godaddy account, might this be the root of the problem?
