The fonts do not load for my site

I love the simplicity and power of this plugin, however, I am experiencing some serious issues with it. My text is completely disappearing in some cases. Usually when this happens, the user has to refresh my site up to 5 times for the text to finally load. This issue will sometimes occur on my desktop Chrome browser, but usually occurs when using the mobile version of Chrome. I really wish I could give this plugin 5 stars, but it is simply not working for me. I’ll be more than happy to give a better rating if someone can help me fix this issue. Thank you so much and keep up the great job, developer!

BTW, I am using the Merriweather Sans font on a Responsive theme. My URL is u-n-i-reeka.com (without the hyphens).
