you can upload the tmpl_xxx directory to templates folder after that log in to admin panel under Settings -> Advance Settings -> Templates you might see a drop down in that you may find your template name. Let me know if you are facing the same problem.
I have an uploaded new template as public_html / templates / tmpl_xxx. Then. I went to Admin Panel >> Advance settings >> change the template. However, why is there only UNI template available, not the new one?
Thanks,
