I recently converted my website to the Responsive Design Shopping Cart Software

Getting the following error message for 18 pages
Text too small to read
Clickable elements too close together
Content wider than screen
Viewport not set

Please help me how to fix it
the site is
www.ShahnazHusainUSA.com

What pages are the errors for. The home page there looks good. Perhaps you have some content on other pages that is not responsive. Such as product and/or category descriptions.
Do the error messages relate to any specific pages?
