I follow the below link to create a template
Everything went fine but after publishing it's showing the blank page in publisher, please help me
I believe you need to use the "allowedTemplate" property. Check the "Template Availability" caution at 
Please verify if anonymous user has read access to /conf folder from publisher useradmin.
If no then please give the access and verify.
Three things to be checked:
1) In publish, check if Edtiable templates are present or not in /conf/ folder , also template script in apps
2) Inspect page and check if any JS error present in console
3) Check publish error.log in case if case any exceptions coming.
Cross check if the Editable template type and the template(In Enabled state) is published.
