Unfortunately, the very first step in our troubleshooter is the issue of
using the correct browser. Roll20 only supports latest-release
non-beta editions of Firefox and Chrome. While Roll20 will work in a variety of browsers, in order to maximize
your playing experience and take advantage of everything that Roll20 can
do, you should use the latest version of either Google Chrome or Mozilla Firefox . That
said, if your player is willing to swap browsers and this issue
continues to happen in the future, you could 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!
