The Trackback feature has been removed starting with Confluence 7.0, per Confluence 7.0 Release Notes.
There is a customization in <confluence-install>/confluence/confluence-WEB-INF/web.xml that is attempting to load Trackback.
web.xml
<servlet>
<servlet-name>trackback</servlet-name>
<servlet-class>com.atlassian.trackback.TrackbackListenerServlet</servlet-class>
<init-param>
<param-name>trackbackStore</param-name>
<param-value>com.atlassian.confluence.links.persistence.ConfluenceTrackbackStore</param-value>
</init-param>
<load-on-startup>7</load-on-startup>
</servlet>
...
<servlet-mapping>
<servlet-name>trackback</servlet-name>
<url-pattern>/rpc/trackback/*</url-pattern>
</servlet-mapping>Solution
Remove the trackback lines above from <confluence-install>/confluence/confluence-WEB-INF/web.xml and restart Confluence
