File Manager uploads fail most often because of browser limits, unstable connections, archive size, quota issues, or uploading into a restricted or invalid path.
Common symptoms
- The upload bar stalls or resets
- Large ZIP files fail but small files work
- You get insufficient space or write errors
Troubleshooting steps
- Refresh File Manager and try the upload again in a private browser session.
- Check available disk space for the hosting account and remove unnecessary files if the account is full.
- Upload large content as a compressed archive, then extract it server-side in File Manager if supported.
- Test another browser or upload method such as FTP or SFTP for large transfers.
- Confirm the destination path exists and is writable.
Additional notes
- Large uploads are more reliable over FTP or SFTP than browser-based transfers.
- A browser tab left open for a long time can hold stale File Manager state.
When to contact support
Contact support if uploads fail in multiple browsers and the account has sufficient free space.
