Hi,
I believed my site was hacked by this guy by the name of Burak Aydin. I logged in to my site today and noticed that my theme has been changed without my permission. This guys have free themes here at wordpress.
Here's the theme that has been installed without my permission:
https://wordpress.org/themes/newsmag
And here's the author's wordpress profile:
https://profiles.wordpress.org/burakkaptan/
I hope that mods here can take a look into this matter. And Burak Aydin, if you are reading this, you are welcome to post in your defence.
