This is a guide on how to get best results in report Bug or Issues. Check also Roll20 FAQ that mentions solutions to many common issues.

If you're unsure, submit issues through Help Center's web form.

Types of Issue

Character Sheets

By Roll20

If you have an Issue with one of the big Official Roll20 Character Sheets such as D&D 5E by Roll20, Pathfinder Second Edition by Roll20, you should check the megathreads for those sheets in the Character Sheet Subforum and report issues in that thread. For issues with any of the other sheet, report though the web form.

Other Sheets

Sheets created by the community or maintained by the publisher should be reported through the preferred method mentioned on the sheet's info page, but if nothing is mentioned on the sheet, post in the Character Sheet Subforum otherwise. Bugs on community-created character sheets are not something Roll20 acts on usually.

Updated Dynamic Lighting

Roll20 does have a Bug Forum, but they seem to be moving away from it, only maintaining a megathread for reporting Updated Dynamic Lighting-related issues, but otherwise only addressing issues reported through the web form.

General

If you have an issue with your account, payment, or want to report a bout to Roll20, you do so though The Help Center's web form. Posting in the Bug Forums will go ignored most times, the web form is the way to go.
