Error Code when Logging Into A Game with Secondary Account

I launched a game with my GM account. Then I opened an incognito window and logged in with a secondary player account and launched the same game. Instead of loading up properly I get the following error: Refreshing the page fixes the issue but this seems to persist and is easily replicated. I should note this is happening on a freshly copied backup of my campaign.

I'm sorry to hear that you're having issues with the site. Could you please carefully work through the first three steps of our guide to Solving Technical Issues ? Step 1: Make sure to use the right browser Please check if these issues persist when using both Chrome and Firefox. Step 2: Ensure that there are no extensions/addons interfering with Roll20 Please disable all add-ons/extensions and anti-virus programs. Step 3: Clear your cache If none of the above succeeds, please thoroughly work through Step 4 . (Don't forget the complete Console Log!) Thank you! Just trying to cover the bases with this but the console log will help the most as an incognito browser shouldn't be running extensions, I think.
