Could you have have your friend complete Steps 1-3 of our Solving Technical Issues wiki page, taking special care to... Temporarily disable all browser add-ons and extensions Temporarily pause your anti-virus, and Try switching browsers (for Chrome/Firefox specific issues) to see if one of those components is causing the problem. If all of that fails, he would need to follow Step 4 , including providing all of the necessary information ( especially the Console Log! ), so that we can further assist you. Thanks!
