Speed Grader won't charge pdfs (Google Chrome)

[mjguilleminot]

Hello, I'm sorry if this is the wrong place to ask, but I'm using Canvas in Google Chrome and suddenly I can't see the docs students upload in the Speed Grader. It keeps loading the file, but never showing it... ¿What could be the problem? I didn't change anything. It's been like this for a week or so.

Thank you in advance,

This sounds like a problem that several people have been having recently with Chrome. In almost every case it is related to an extension installed.

Here are links to some of those threads where troubleshooting the issue is discussed.

• Speed Grader Not Working in Chrome 
• Ghostery prevents speedgrader from showing submitted documents 
• PDF Preview broken on Chrome

Some of the known extensions causing problems are adblockplus, ghostery, honey, bitdefender. There have been some others reported as well.

Thank you very much! It was Ghostery...
