Hello,

I have an issue with how the website is displayed while using certain browser.

The website displays fine on safari and chrome on mac desktop.

However, when the website is displayed on safari on my tablet, or internet browser on my phone, the logo on the header is not displayed. The color is also displayed differently. (i.e. the menu has a dividing lines. The certain area of the website is displayed in dark color background where it should be displaying white background. Will you help me?
