You see this page probably because you sent a wrong email asking for a theme support.
For any help, theme support or just information regarding Matrix themes, I kindly ask you to use the form from the following page:
Why should I use the form from support page?
If you're using the same email used for purchase or previous support enquiries, your email quite often ends up in spam folder or in folder "closed issue"
I used the form from support page but have never received an answer
Probably you wrote a wrong email in form
How do I add a screenshot?
You don't need to add a screenshot in your first support request. It can be sent later if necessary.
Do I need to provide a website access too?
You should provide the website access if it requires any help or support directly in admin mode ( HTML or JS )
