Hi,

I have received an email from my hosting company that my account is partially suspended for sending spam in large quantities while I haven’t sent a single email anywhere.

The email also says:
We understand that you may not have sent the emails yourself. It is possible that an attacker was able to exploit the script to improperly use your site to send emails on your behalf. We strongly suggest that you evaluate this script for weaknesses and update it to the most recent version available if its a commercial script.

Can you please let me know what script from the theme is causing this and what should I do about it?

Thanks.
