I want to solve the issue which happened after installations of W3Total plugin

Hi,

Thanks. I have used one w3 total cache plugin and after that it delete my some icons from the website which you can see on the slider, in the search box below the sliders, Our Latest Holiday Packages (slides button) and at the email id which have mentioned at the footer part. Could any one please tell me that how can I remove this error. I searched a lot for this errors but all are waster. Please any one can tell me how can I fix those issues and I bought this theme from the themeforest and below is the link of my website and the demo theme on themeforest.
