Hi all,
I have been using Osclass for over a year and have never had any particular problems.

with this theme i can't send email.
Any type of email (password recovery, user created or otherwise) will not sent.

I did various tests and I really don't know what else to do:

- installed on a different Hosting with Blender theme(and email work)
-install on same server different theme (and email work)
- tried the mail server settings with Gmail (not work)
- Provided the settings of the servermail with SSL
-test servrmail settings without SSL
-tried leaving the settings empty
- I tried to replace the oc-includes folder with that of another working installation, but the problem is not solved.

No errors are generated in PHP errors, how can I solve them?

the site in question is
www.armeriaonline.eu

The problem is on the Theme Stela, if i change theme it work.

Change your gmail account. Google limits the number of emails sent and blocks sending.
