3 of my campaigns broke

Players can't edit character sheets, and are also unable to move tokens and the like

There's not a lot of information to go on here. Are the character sheets assigned to them and are they in their journals? How are they trying to open them? Are the tokens assigned to character sheets that they control? Are the tokens on the token layer? Is this something that has just universally affected three games that used to work?

Hello Xavier P., I am sorry to hear that you are unable to edit characters and moving tokens.  Can you provide us a screenshot of the Character Sheet Settings for who is allowed to edit the tokens with this issue? Please provide us the name of the affected campaigns as well.  Additionally, to be able to rule out potential causes,please carefully  work through the following 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. 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!
