Let's get you a leg up on the process and start with the first three steps of the 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, thoroughly work through Step 4 . (Don't forget the complete Console Log!) Most Mods will toss this to you to start out with as the process of gathering information about the issue. A Mod will be around sooner or later but it will make their jobs easier if you already started this.
