Hi
I just have installed socially viral theme for my blog. Everything is fine but I am amazed why the written words in menus, pages and posts are missing?

I have tried everything even import the theme settings, disable all plugins one by one. all the things are working what ever widget and post and video i add it appears on the site but the words not show up. not on menus not the posts. even the theme has sample page i can click sample page because the box is slightly visible and click able but i cant see the written words ” Sample page” and when i click the sample page all words are visible but when i write posts or make menus or write any text on widgets etc nothing shows up? Kindly help me.
