Hi,
Since I still had an account on your website, I looked into it directly.
One problem you have on your website is the file templates/YOUR_TEMPLATE/error.php which is a custom error page of your Joomla template which doesn't properly display error messages.
So, on your screenshots we can't see the error message.
I renamed that file to error_old.php and now, if you redo the process I talked about in my previous message, you can see the error:
Unterminated comment starting line 2
/home/ofertaex/public_html/abierto.uy/media/com_hikashop/mail/new_comment.html.modified.php:2
Call Stack
# Function Location
1 () JROOT/media/com_hikashop/mail/new_comment.html.modified.php:2
2 hikashopMailClass->loadEmail() JROOT/administrator/components/com_hikashop/classes/mail.php:32
3 hikashopMailClass->get() JROOT/administrator/components/com_hikashop/classes/vote.php:558
4 hikashopVoteClass->sendNotifComment() JROOT/administrator/components/com_hikashop/classes/vote.php:337
...
What this says is that you have customized the "new comment" email in the System>Emails in an incorrect manner.
Then, if I check the email there, I can see this code at the beginning:
