Hi Mrzusho,

It seems that you have used some bootstrap plugin and it is overwriting some CSS code in the main style.css file of the theme what you do is just login to your admin site and Go to Appearance -> Theme Options OR Customize -> Design Options Tab -> Custom CSS paste the following CSS code and Click on save all changes button:

#access a {
    box-sizing: content-box;
}

Thank you!
