Is it Magento?

Yes.It is Magento.

Are you looking for a free or paid support?

We acquired the Logange Template with you and have a doubt, do we need to pay for support?

I mean, first of all, I’m not the author of the theme. Secondly, this is a customization so you need to get paid support.
If you’re interested in, drop me an email to gmail(at)moskvayigit.com for the details. I could fix it in few hours if we agree to work together.
