Document Mod
Inline preview for PDF, TXT, and Markdown only (not Office). Default on. Tiers need Show documents.
Document Mod
Site-wide master for inline document preview on public download pages. When off, document preview URLs are blocked and Users limits Show documents has no effect.
Supported: PDF, TXT, and Markdown only. Word/Excel/Office files are not previewed (the Mods section description may mention Office, but the code does not).
PDFs use the browser's native viewer; TXT and MD render on the page.
Where to find it
Admin → Settings → Mods → Document previews → Document Mod
Setting key: toggle.document_mod
Default: on (unset = enabled)
How it works
Preview shows when: this mod is on, the viewer's tier allows Show documents (Users limits row Document viewer), the file is PDF/TXT/MD, and password/premium gates pass.
Common problems
DOCX or XLSX shows no preview
Unsupported type. Convert to PDF or leave download-only.
