GiGs said: I've only seen that happen when there was an error at roll20's side. There could be an issue with your campaign, or with your script, or something broader. I'd try the following thigs Try to add another script, any script, from the One-Click install. Say token-mod - it's reliable. If you can't install it, thre's an issue with your campaaign and you need to contact roll20 ( <a href="mailto:team@roll20.net" rel="nofollow">team@roll20.net</a> ) You can also create a completely new campaign, and try to save your script there. And also add any other script. If you can't do any of the above, there's a wider issue with your account and you definitely need to contact roll20. If you can install other scripts fine, but it's just your script, then there's probably an issue with it and maybe post the code so that we can seeif something's up. Thanks for the tips! I created a clean campaign and chose a basic script from the Roll20 scripts and it works. I was trying to use the D&D Beyond importer script, but I can't get it to work yet. I guess I'll just redo my campaign from scratch. I appreciate your help.
