Introduction
You can install third-party templates to customize the appearance of your webstore after purchasing them from the marketplace. These templates are created by third-party developers and can be installed on your webstore to change the look and feel of your webstore.Install Third-Party Template
To install a third-party template:- Purchase a third-party template from the Marketplace.
- Make a backup of your current theme settings by using SFTP or File Manager. You can also press “Create a Theme” button to make a backup of your current theme settings.
- Go to your admin panel and click on the Themes tab.
- Click on the “Install Theme” button.
- Wait for the theme to be installed.
After installing a third-party template, you can customize the appearance of your webstore by editing the theme settings.Keep in mind that some third-party templates may require additional setup steps. Make sure to read the documentation provided by the template developer.
How the Install Runs
Theme installation is asynchronous — the request returns immediately and a background job carries out the work. A progress modal in the admin shows the current stage in real time, and the page does not need to stay open for the install to complete. The job runs through these stages in order:| Stage | What happens |
|---|---|
| Downloading | Fetches the theme archive from the marketplace using your license key. |
| Validating | Validates the ZIP for size, path traversal, file types, and free disk space (requires ~3× archive size). |
| Backing Up | Snapshots the current theme (frontend/ + public/assets/) before any file is touched. |
| Extracting | Replaces the live frontend with the new theme’s files. |
| Configuring | Writes the frontend .env (API URL, store URL) for the new theme. |
| Restarting | Restarts the frontend process so the new theme is served. |
| Health Check | Waits for the frontend to respond as healthy before marking the install as completed. |
Automatic Backup and Rollback
Every install automatically backs up the current theme before any files are replaced. You do not need to make a manual backup unless you want an extra off-server copy.
- The job is marked as failed with the exact error in the progress modal.
- The previous theme is automatically rolled back from the backup taken in the Backing Up stage.
- Your store keeps running on the previous theme — there is no broken in-between state.
Archive Validation
The platform pre-validates the theme archive before extracting anything to prevent broken or malicious uploads:- Size limit — archives over the configured maximum are rejected.
- Path traversal protection — entries with
..or absolute paths are rejected. - File type allow-list — only theme-relevant file types are allowed inside the archive.
- Disk space check — the install is refused if the host does not have at least 3× the archive size free.
Logs and Install History
Every install attempt is recorded inThemes > Logs, including:
- The theme ID and triggering admin.
- The final status (completed / failed) and the failure reason if any.
- Per-stage messages with timestamps, useful for diagnosing issues with a specific theme.
Third-Party Templates Features
Keep in mind that some third-party templates may not include all the features of the default theme. Make sure to check the features of the template before purchasing it.MineStoreCMS provides a default theme that includes all the features of the platform. You can use the default theme if you want to have access to all the features of the platform.
