A useful diagnosis starts with a reproducible description. Gather the details before requesting help.
Prepare an actionable diagnosis
Include Core version, active Template, relevant Extensions, language, browser and action. Describe expected and observed results. A screenshot can help if personal data is hidden. Never send passwords, tokens, private keys or configuration files containing secrets.
Checks before reporting
First check publication status, link activity, language and Block Assignments. For installation errors, retain the exact message and package version. For layout issues, state screen width. These checks make a support request actionable.
