Hi @tuanphan
The website is in my post: www.mrmedical.com.au
Sorry I didn't describe the problem correctly. And I solved the problem of disappearing blog sidebar by removing some code injection I added long ago.
The problem is actually with the Blog sidebar content.
As mentioned, I have 3 blogs and I want the sidebar to display a summary (a list of posts) for that active ( currently displayed) blog.
But now when I set the side bar summary content to Health News blog for example, if I go to Tin Sức Khỏe, the side bar summary is still from Health News, it doesn't change.
So the question is how do I display a Summary on sidebar that pulls data (posts) from the blog that is currently displayed (not fixed to one blog)?
Same thing with the Search box. It points to a blog and doesn't change when viewer switches from one blog to another.
Thanks if you can help me with a solution Tuấn
