Using WPtouch 1.9.5 and WordTwit 2.2.4. When I select the Twitter link there is an error message that appear under my avatar and Twitter link:
Warning: Invalid argument supplied for foreach() in /home/.freakmeister/me/portfolio.davesharpe.com/wp-content/plugins/wptouch/themes/default/header.php on line 169
This appears on every installation I've set up using both plugins. Not a big deal since it's barely visible.
By the way, thanks for both of these great plugins.
