Ok, will check it out.
Check the file and folder permissions for the Sentastico module folder. Should be 777 and owned by http:http (Or whatever the apache owner is in CentOS) I use Ubuntu, so it's is a little different.
Also, on another note, you should NOT be accessing the panel using IP! (As explained in our docs) You should be accessing it using a sub domain like panel.domain.com
