When you visit the main site, the icons for Facebook, Twitter, LinkedIn, YouTube and RSS feeds all look right and link to the right place. For example, the Facebook icon URL is http://tutordoctorsanfrancisco.com/wp-content/plugins/social-profiles-widget/images/default/Facebook_32x32.png
When you visit an add on domain, the icons are missing and the alt text links go to the right place. For example, the Facebook icon URL becomes http://tutoringindanville.com/wp-content/plugins/home8/tutordoc/public_html/wp-content/plugins/social-profiles-widget/images/default/Facebook_32x32.png.
Please notice the difference between the two icon URLs. The correct link for Tutoring In Danville is http://tutoringindanville.com/wp-content/plugins/social-profiles-widget/images/default/Facebook_32x32.png.
On the hosting account for these domains, I have set up all the add on domains to be symbolic links to the main site.
What do I have to do to fix this problem?
