Re: Google ads
It looks like you’re using WPMU’s default Text widget and pasting the Google AdSense code within that. The widget’s output references a CSS selector (class=”textwidget”).
You need to use CSS to postion properly the AdSense output. You have three options:
1. Place inline CSS into the widget’s text field
2. Customize the textwidget selector
3. Create / or add to your own custom CSS file a new class called, for instance, my_ads. Then, reference that selector in the widget’s text field
