Introducing, my name is Aisyah Gray from Indonesia. I am a blogger who has more than 5 years experience. I have a website about Android smartphones ( https://www.samsungstarters.com/ ).
The site that I have uses Wordpress. As we all know, WordPress has a theme and plugin system. But sometimes the themes and plugins that we install require modification.
