Jamal, please describe and provide screenshots to the problem that you are having. What do you mean by "can not install Social Media Button"? Are the buttons showing up or they are not showing up in a way that you want them to be?
If you are having problems with social media button plugins that insert the buttons before or after a post, you can give DiggDigg a try. It basically installs a set of floating buttons beside your blog posts irregardless of the theme that you are using.
Haha... It's true that Wordpress is the most user-friendly CMS on the Internet but there are still many problems that users may come across especially when they are new to setting up a self-hosted blog or the blog they own involves a lot of customizations (codes, themes, plugins, etc.).
