I have problems sending emails within the opentcart system.
Before I arrived.
New user emails arrive perfectly.
I lack something in the folder where files are email as sales, mail, does not appear the box to send a message.

I've been looking for the file but can not find. Where's that file for uploading it again
The other...
I installed two extensions because the mails came very messy and not looking good
It seems that all is well and I see installed correctly but failed to fully get emails
