Duplicator Pro 4.6.5

• [NEW] Staging: Staging site database tables are now removed when uninstalling the plugin with “Delete plugin settings” enabled
• [UPD] Staging: Updated Uninstall settings descriptions to clarify what each option deletes, including staging site data
• [FIX] Staging: Fixed staging-site backups including wrong database tables — backups created on a staging site now correctly contain only that site’s own tables
• [FIX] Staging: Fixed restoring a staging-site backup onto a normal site leaving the destination deindexed with outbound email blocked

[FIX] Storage: Fixed Dropbox chunked uploads failing permanently when a resume attempt found a gap between the local and server offset, by automatically recovering from Dropbox incorrect_offset errors and reworking the upload into a timeout-driven append loop

[NEW] Backups: Added a cron-based fallback that automatically resumes package builds when the primary loopback kickoff fails silently, preventing backups from stalling on constrained servers

PHP Version: 7.4+
WordPress Version: 5.3 or greater.
Tested up to: 7.0

• This release fixes a problem where some hosting environments appeared to support background backup processing but actually didn’t, causing backups to silently stall or fail during creation. The detection check now verifies that background processing genuinely works before relying on it, so backups run reliably on affected hosts.

BASE [LITE]

• [FIX] Backups: Fixed the background-processing capability test giving false positives on hosts that drop non-blocking connections, which caused backup builds to silently fail; the check now confirms the background worker actually ran, and any stale test result is reset automatically on plugin upgrade

[FIX] Base: Made upgrades from older installations more reliable by handling missing custom-path settings gracefully.
[FIX] Migration: Fixed the import settings screen wrongly reporting a save failure even when settings were saved successfully.

PHP Version: 7.4+
WordPress Version: 5.3 or greater.
Tested up to: 7.0

• This release resolves two compatibility problems introduced in 4.5.26. On some sites, plugins or themes that customize the WordPress admin footer (for example the Avada theme) could prevent Duplicator’s admin pages from loading; those pages now open normally. In addition, updating Duplicator from an older version (4.5.25.4 or earlier) could fail in rare cases involving other active plugins; that update path is now handled safely.

BASE [LITE]​

• [FIX] Base: Resolved a compatibility issue that could prevent Duplicator’s admin pages from loading in 4.5.26 when another plugin or theme set a non-text value in the WordPress admin footer
• [FIX] Base: Improved reliability when updating Duplicator from version 4.5.25.4 or earlier, preventing a rare conflict that could interrupt the update on sites with certain active plugins.

Duplicator Pro Version 4.5.26

• [NEW] Storage: Added SCP-mode transfer support to the FTP/SSH storage layer.
• [NEW] Migration: A Pro site can now correctly restore a backup created by the Lite version — the deployer injects the addon code the Pro installer needs, so cross-variant imports, restores, staging, and recovery run reliably. (Installer)
• [NEW] Staging: Added installer-side staging-site detection during restore, warning users before overwriting or migrating onto a staging environment, with staging page and admin-bar UI refinements. (Installer)
• [UPD] Storage: Instead of blurring the entire storage page when a cloud provider isn’t licensed, each unlicensed storage type (S3, Dropbox, Google Drive, OneDrive, FTP/SFTP) now appears individually as disabled with its own upgrade link, so available storages stay usable.
• [FIX] Schedules: Fixed scheduled backups silently retrying forever when they failed before a package could be created (e.g. a missing template) — the schedule now advances, records the failure, and emails the user; also fixed storage-transfer failures not triggering notifications.
• [FIX] Schedules: Fixed the schedule “Run Now” action hanging instead of redirecting to the packages page.
• [FIX] Schedules: Schedule failures now record an error-severity activity-log entry (so the “Failed Backups Detected” notice links to a populated list), and fixed a fatal crash saving the log entry when a schedule referenced a deleted template.
• [FIX] Schedules: Fixed a nonce-action collision in the schedule storage-links endpoint.
• [FIX] Storage: Fixed a fatal error in OneDrive uploads where the response body was accessed with array syntax on a response object during failure logging.
• [FIX] Storage: Fixed a PHP error rendering the SFTP storage global-options section (a reference to an upload chunk size the SFTP storage never provides).
• [FIX] Staging: Fixed the WordPress Customizer preview on staging sites staying blank with links marked unpreviewable (WordPress core rejects URLs containing /wp-content/), while keeping core’s URL-safety checks for other URLs.
• [FIX] Staging: Fixed staging sites never being auto-detected as complete (top bar stuck on “Creating…”), and restored consistent staging admin-notice spacing.
• [FIX] Staging: Fixed a fatal parse error on PHP 7.4 caused by a mixed type hint in StagingPackage.
• [FIX] Multisite: Fixed the package-setup Security tab on multisite showing “You can’t exclude all sites” instead of the security settings.
• [FIX] Base: Fixed license-tier selection during cross-license imports so PRO and ELITE correctly outrank BUSINESS and GOLD. (Installer)
• [FIX] Base: Fixed a fatal error during upgrade when migrating legacy trace-log options stored as strings (could crash installs upgrading from before 4.5.23-beta1).

[FIX] Fixed a bug that in some cases caused a false-positive “build stuck” error.
[FIX] Fixed staging site creation failing when the source backup used archive encryption

[UPD] Raised Google Drive upload chunk size default from 256 KiB to 8 MiB for improved upload performance.
[UPD] Improved visual indicator for successful storage connection tests.
[UPD] Improved color contrast for better accessibility in admin UI elements.
[FIX] Fixed an issue where a failed upload to one storage could block all remaining storages indefinitely, preventing backups from completing.
[FIX] Fixed OAuth token refresh for Google Drive, OneDrive, and Dropbox where a temporary server failure could permanently break storage authorization.
[FIX] Fixed the storage list page crashing when a cloud storage provider returns an unexpected error during validation.
[FIX] Fixed the support toolkit’s “Failed Backups” download being empty when accessed more than 6 hours after a backup failure.

PHP Version: 7.4+
