I just checked this new feature: When I edit a template other than wireframe, in the overriding path, it doesn't indicate which template this file is originally from. Can you explain how so?
It should respect the default site(frontend) template as what you set from the backend.
Is wireframe still a special template which share some of its files with other tempalte? How to create my own template?
Yes, this behavior is still the same as the previous version.
Do you mean that you would like to create another Easyblog theme for Easyblog? If yes, you can refer to the Easyblog default Wireframe theme and what the file structure looks like.
I had a custom template before upgrading to 6. It worked well.
Now although in the category setting it is still selected as the template but it seems none of its files is in effect. For example
html/com_easyblog/themes/MYTEMPLATE/blogs/entry/default.posts.php
I wrote some custom code in this file, now where should I apply them?
It should be the same as what I guided you last time
