I used the same server setting I previously used with universal email and ecart 4. In a previous thread you wrote
"previously you had said you have universal email 4. with eCart 6, that should not be installed.
if you have both UE 4 and eCart 6 installed it will cause conflicts.
recreate the users configuration folder to start from scratch, then install only eCart 6."
So I removed it.
I pasted the server info I currently use with my other ecart sites in a pm.
