Whenever I try to synchronize, I get the following error:

Fatal error: Cannot access empty property 
in ...child/administrator/components/com_wcp/helper.php on line 1419

However, everything is working fine, I just go back the page (error page) and 
check 
my child site, it is synchronized.

I really like this extension.  It's very nice.

Same problem here (the error in line 1419).

I also have an error when trying to revert. Then the error is:
Catchable fatal error: Object of class stdClass could not be converted to 
string in
/root/to/mysite/htdocs/child/administrator/components/com_wcp/helper.php  on 
line 1236.

I have the same site on my local server and on a remote server. In my local 
server,
everything works fine. The problems are in my remote server, so I guess it is
something with the php definitions. But which??

I also noticed that in my local server, in 'differences' page, when I have a new
update - the word 'UPDATE' is in red and I also get the reference to the id of 
the
changed element. In my remote server - no red color and no id reference.

Hi there,
i've fixed this issue changing the line 1419
in the file ./child/administrator/components/com_wcp/helper.php

from
$db->setQuery("delete from #__log_queries where table_name = '$child_table' and 
value = '" . $master_row->$key . "' and date > '$internal_timer'");

to
$db->setQuery("delete from #__log_queries where table_name = '$child_table' and 
value = '" . $master_row->key . "' and date > '$internal_timer'");

Notice the change from $master_row->$key to $master_row->key

Hope this helps someone,
Massimo
