Tried it in a community version (2.2.4). Did not work. It just showed the words on the top and down the left side of top.
Since I backed up the overwritten file I was able to restore with no problems.
there is ok for cscart_v2.2.4-community? I install by your steps but it can no working well at cscart_v2.2.4-community.
Wait for your reply.
