You guys had updated my theme and I started facing this issue and I tried to change the from email address and it worked for once then it dont send me emails, but it sends to the customer about order. I contacted my hoster and did troubleshoot and they assured me nothing is wrong with the hosting or email configuration, they checked the logs, and verified that there is not an issue with mail sending from the sales@mototorque.in and we installed SMTP plugin as they suggested but still nothing working so they told me to contact you guys because they tell me the problem is with the theme or plugins. Please help
