I have the same problem in my env (Liferay 6.2 EE) when finishing to install the Liferay Audience Targeting.lpkg from the backoffice .
when clicking on audience targeting in site configuration, i have a blank page with the following error in the log
javax.portlet.PortletException: com.liferay.portal.kernel.template.TemplateException: Unable to process template content-targeting-web_SERVLET_CONTEXT_html/content_targeting/view.ftl -
ERROR Template processing error: "Expression tabs1 is undefined on line 23, column 18 in content-targeting-web_SERVLET_CONTEXT_html/content_targeting/view.ftl." -
ERROR Template processing error: "Expression tabs1 is undefined on line 23, column 18 in content-targeting-web_SERVLET_CONTEXT_html/content_targeting/view.ftl."
Any help in this issue will be appreciated
Thanks in advance
