working copy not showing differences

[[email protected]]

Hi,

I have installed working copy in the master and the child sites. I can see the child I created in both sites, but I cannot see the buttom "differences".

for your info: I could not create a child if I checked database and file transfer, because of a memory limit issue. So I copied the database and files of the master site to a subdirectory withing the public_html of the master site using akeeba. After this, both sites seem to work OK. So I created a child using working copy, and specifying not to copy database and files since these were already copied with akeeba. I also created a child in the child site in the same way as in the master site.
I made a smal change in an article in the child site and checked if I could see some changes in the master site and I didn't see anything. Not even the buttom "differences" of working copy.
Please can you give some advice how to proceed?
Kind regards
