Setup & status
ZephyCube PDF v1.7.1
Most tools run entirely in your browser, so they work the moment the site is uploaded — no configuration needed. A few tools rely on helper programs on the server. Here's what this host currently has:
First-time setup: the settings file ships as
config.example.php so an
update never silently overwrites a live site's settings. Rename it to
config.php in the site root — that's what actually gets loaded.
| Program | Status | Powers |
|---|---|---|
| Shell execution | Enabled | Required for every server-side tool |
| Ghostscript | Installed | Compress PDF, and password protect as a fallback |
| LibreOffice | Not found | Word / PowerPoint / Excel to and from PDF |
| qpdf | Not found | Protect PDF and Unlock PDF |
Enabling the server tools in cPanel
Shared hosts vary. On most cPanel servers you can:
- Confirm
exec()/shell_exec()aren't indisable_functions(MultiPHP INI Editor, or ask support). - Ask your host to install Ghostscript and qpdf — both are small and common.
- LibreOffice is larger; some shared hosts don't allow it. If unavailable, the Office conversion tools will show a friendly notice and the in-browser tools keep working.
If a program lives at a non-standard path, set its absolute path in config.php (the $ZC_BIN array — remember this file starts out as config.example.php until you rename it, see below).
Folder permissions
The tmp/ folder must be writable by PHP (typically 755 or 775). Uploaded files for server tools are written there and deleted right after processing.
