Duplicator Pro 5.0.6

FIX: Base: Prevented Duplicator page-specific scripts and vendor dependencies from loading on third-party WordPress admin pages, reducing potential conflicts while preserving global styling and dismiss functionality.

NEW: Base: Added AI Ready support through the WordPress Abilities API, with a Tools → AI page and abilities to list Backups, create full or database-only Backups, and monitor their status.
NEW: Backups: Introduced AutoTune, which runs real test Backups to find a reliable configuration for the current server, reports host-level issues, protects active sessions, and automatically pauses and resumes schedules.
NEW: Backups: Added centralized pre-backup validation for archive engines, compression, encryption, database engines, server requirements, paths, and leftover installer files, with safe defaults and automatic correction of unavailable settings.
NEW: Backups: Added unified failure notices with plain-language explanations, troubleshooting guidance, documentation and Activity Log links, AutoTune recommendations, and one-click fixes where available.
NEW: Backups: Added resumable gzip compression for database dumps, reducing Backup size and improving reliability for large databases on time-limited servers. The installer now decompresses these dumps before restoration. INSTALLER
NEW: Backups: Added a shared Backup Request API that lets supported integrations create safety Backups and monitor their status before destructive operations.
NEW: Storage: Added Duplicator Cloud support to Lite, including off-site storage, remote download and Restore, cloud recovery metadata, and account connection through a storage token.
NEW: Upgrade: Moved Lite onto the shared Duplicator engine and added automatic migration of legacy Lite Backups, settings, filters, installer security, naming preferences, consent choices, and dismissed notices.
UPD: Base: Restored in-plugin notifications across Pro and Lite, with safer cache cleanup during upgrades, variant changes, reactivation, and Debug resets.
UPD: Backups: Redesigned the Backups list, Backup Details, New Backup, and Template interfaces with environment snapshots, phase timings, clearer security controls, normalized status flags, improved remote actions, and responsive layouts.
UPD: Backups: Improved worker reliability with automatic HTTP Basic Authentication detection, dual SQL/file process locking, retryable loopback detection, consistent creation guards, and better diagnostics for interrupted background processes.
UPD: Backups: Persisted the exact build options and execution origin used by each Backup, ensuring progress, telemetry, details, schedules, WP-CLI, AI, and legacy records report consistent information.
UPD: Backups: Removed the obsolete Share button and Backup File Links dialog while retaining the existing Download, Build Log, Activity Log, and Delete actions.
UPD: Storage: Storage connection tests now show the provider’s actual failure reason. Duplicator Cloud discovery and connection controls were improved, and unknown providers are hidden without deleting their saved records.
FIX: Base: Hardened administration, logging, and upgrade handling to prevent sensitive Backup paths, hashes, secrets, and raw failure details from appearing in PHP logs or user-facing messages.
FIX: Base: Updated bundled PHP and JavaScript dependencies to address published security advisories.
FIX: Base: Prevented secondary error-handler failures during plugin updates, preserved addon state during hash-only upgrades, delayed cron translations until safe, and prevented the admin bundle from replacing WordPress’s jQuery instance.
FIX: Base: Corrected broken external links, Screen Options alignment, security-control hover states, storage-table borders, and notices that displayed literal HTML. INSTALLER
FIX: Backups: Fixed silent database-only archives caused by empty or root-level file filters, emoji loss in mysqldump exports, late cancellation of completed Backups, non-fatal database progress estimates, and incorrect engine details on legacy Backups.
FIX: Backups: Improved browser-side timeout, network, authentication, proxy, and invalid-response errors, while increasing the scan request window for slower servers.
FIX: Migration: Corrected database build-mode metadata so mysqldump Backups with excluded tables restore correctly.
FIX: Storage: Prevented completed Duplicator Cloud uploads from being incorrectly marked failed and removed. Also contained malformed OneDrive responses and corrected upload/download wording and chunk-size unit labels.

This release improves the consistency and reliability of diagnostic logging.

[FIX] Multisite: Added validation that prevents imports when a backup contains no eligible source site (Installer)
[FIX] Multisite: Made subsite creation safe to retry after interrupted extraction and restored URL-collision validation (Installer)

[UPD] Backups: Disk-full and quota-exhaustion errors are now detected and reported consistently across installer build, database export, and all archive engines, with centralized user-facing messages (Installer)
[UPD] Storage: Google Drive storage no longer passes the refresh token to the Google SDK client, preventing an unhandled exception when the SDK attempted auto-refresh without client credentials
[FIX] Multisite: Fixed multisite subsite import hanging indefinitely on the “Parameters update” step when a source-site mapping entry was missing (Installer)

[FIX] Backups: Resolved a multisite edge case where a build started from a subsite could conflict with one started from the main site

• [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
