Player can't edit sheet

One of my players can't see the character sheet to edit it. All of my other players can edit theirs just fine but he gets a white screen. I've deleted his character and made a new one, and I've already added him to the list of players able to edit this sheet. Anyone have a fix?

Before we dive into the guts of the issue, we're going to need him to do a few things for us, things that often fix issues for users before more extensive troubleshooting is needed. Can he please follow Steps 1-3 of our Solving Technical Issues wiki page (temporarily disable all browser add-ons and extensions, temporarily pause any anti-virus, and try switching browsers (for Chrome/Firefox specific issues) ) to see if one of those components is causing the problem. If none of that resolves the issue, have him follow Step 4 , so that we can have this information to further assist him.

OK thanks. We've tried disabling antivirus and adblocker, as well as a new browser. We'll try the add ons, too, though.
