I installed DiggDigg sidebar on my Debut Theme (Press 75) and now my sidebar and footbar are gone. The whole site is misplaced and I receive this message in the sidebar:
Fatal error: Call to undefined function dynamic_sidebar() in /home/content/11/7729011/html/wp-content/themes/debut/sidebar.php on line 22
I uninstalled the DiggDigg plugin but nothing changed. Alas, I was also stupid and hadn't backed up recently.
