after moving back from blogger, categories and archives show only one post

Greetings

I’ve moved my blog to blogger, then years later came back from blogger again to wordpress.
But I noticed that, after moving back, categories and archives now show only one post in each!
I have several posts in each of those:
http://my2cents.gawaher.com/category/english
http://my2cents.gawaher.com/date/2012/02
I don’t know why only 1 post is showing there..

Can someone help me please?
Many thanks.
