First thing, please try our general troubleshooting steps (1-3) outlined in the Solving Technical Issues article. If those do not work, additional troubleshooting steps for API issues are outlined below: Check both your browser console log and the API Output Console for additional information and errors Review script-specific information on the GitHub library and API Forum Try logging out and logging back in to your Roll20 account Troubleshoot only one game at a time - close all other instances of Roll20 that are not related to that game Use two windows/tabs of Roll20 for troubleshooting - one for the API Output Console and one for entering the game Restart the API Scripts Sandbox Verify your scripts are updated Disable scripts one at a time Remove and re-install the scripts Review the script syntax (i.e. Is all the spelling correct? Are you missing characters or do you have extra characters?) Double check your script and/or character sheet dependencies and review scripts for conflicting items (i.e. Do they require other scripts to work? Do they need a specific updated character sheet? Can these scripts work at the same time? Are they utilizing similar functionality?) Sorry for the trouble, let us know if none of this helps and we'll continue to assist.
