Hello,
Cufon takes some time to load on server that's why this problem is occurring, Go to js > custom.js present in your theme directory and remove the code given below

Code:

//Cufon replacement
Cufon.replace('h1',{hover: true})('h2',{hover: true})('h3',{hover: true})('h4',{hover: true})('h5',{hover: true})('h6',{hover: true})('.contentbtn')('.content_info')('.readmore',{hover: true})('.submit',{hover: true});

This will solve your issue.
