Reporting a problem

Two places, and they are good at different things.

The community forums

The Site Designer forum is public and usually fast. Long-time users answer there, and so do CoffeeCup staff. Every article in this section came from a thread there, which is the best argument for its usefulness: the menu that vanished at tablet width was diagnosed by another user in a couple of replies.

Good for: “is it just me?”, questions about how something works, and problems someone else has probably already hit.

Support

Contact support for anything account-related or private: licences, purchases, and bugs you cannot discuss in public. The team answers Monday to Friday.

Good for: licensing, payment, and reproducible bugs with a project file attached.

What to include

The threads that get answered quickly all carry the same details. The ones that stall are missing them.

IncludeWhy it matters
Version and build from Help → About”5.1 build 3626” tells them exactly what you are running
Operating system and versionSeveral known issues are specific to one platform
What you did, in orderTurns “it crashed” into something reproducible
A screenshotEspecially for anything visual, and for warning dialogs
The project file where you can share itThe single most useful attachment for a layout problem
Project size for performance issuesNumber of pages and rough file size
