   Restore Completed

3.1

• Restore Reliability: Fixed PHP fallback database imports on hosts where proc_open is disabled so comment-prefixed SQL table definitions are imported correctly.
• Restore Safety: Database import errors now stop the restore and surface a clear failure instead of logging Restore completed.
• Restore Validation: Restore now verifies the imported siteurl option before running URL replacement.

3.0

• MAJOR UPDATE — please install. Older versions will stop working soon as the legacy backup endpoint is retired. Update now to keep backup and restore functional.
• Redesigned Admin UI: New tabbed Backup / Restore interface with clearer steps, inline help, progress card, and a yellow notice banner that surfaces the email/restore-code reminder after a backup completes.
• Simpler Restore Access: Backup now uses your email and sends an 8-character restore code when the backup completes. Restore takes only that code — no separate email field needed.
• Pre-Flight Disk Space Check: Backup and restore exit early with a clear message if there’s not enough free disk space, instead of failing midway.
• Backup Security: Files continue to be encrypted (AES-256) before upload, with improved key handling behind the scenes.
• Retention: Backup availability is now consistently 48 hours.
• Backup Reliability: Improved backup stability on sites with plugins that interfere with long-running background tasks.
• Restore Reliability: Improved restore stability when plugin code, locked folders, or stubborn file permissions would previously interrupt a migration.
• Security: Removed the old legacy access path and tightened the restore flow.
• Compatibility: Existing backups from the previous version remain restorable during the short upgrade window only.

2.6.1

• Critical Fix: Fixed fatal Call to undefined function OCM\ini_set() crash on shared hosts that disable ini_set/ini_get via disable_functions — this was a 100% restore blocker on affected cPanel hosts
• Critical Fix: Fixed “OS: Windows” log message being written 250+ times per backup on Windows/XAMPP hosts — now logs only once per session
• Bug Fix: Fixed fatal crash when Stop & Reset is clicked mid-backup — background process now re-creates the temporary directory if it was deleted

2.6.0

• Critical Fix: Fixed DivisionByZeroError crash during database backup when tables report 0 MB in information_schema (affected Gravity Forms and other small tables)
• Bug Fix: Changed error catch from Exception to Throwable so PHP 8 DivisionByZeroError is properly caught by the fallback handler
• Log Noise Reduction: Added error deduplication to suppress identical PHP errors from being logged 30+ times per session (e.g. theme/plugin bugs)
• Log Noise Reduction: Suppressed per-table “Table being backed up” log messages that generated 50-80+ lines per backup on large sites
• Log Fix: Fixed misleading “Bucket created” log message that appeared after AWS 502 errors — now correctly says “Retrying bucket creation”

2.5.9

• Maintenance Mode: Automatically enables maintenance mode during restore to prevent visitors from seeing broken pages, white screens, or database errors
• Admin & API Bypass: Admin users and REST API requests (e.g. progress polling) bypass maintenance mode so the dashboard stays functional
• Progress Indicator: The admin progress endpoint now reports maintenance mode status so the dashboard indicator works
• Auto Cleanup: Maintenance mode is automatically disabled when the restore completes or is cancelled via Stop & Reset

2.5.8

• Timeout Fix: Reset PHP time limit before each major operation (archive, encrypt, upload, download, decrypt, extract) to prevent timeouts on large sites
• Upload Fix: Upload timeout now uses the full execution budget instead of the exhausted background process remaining time
• Download Fix: Restore file downloads now use the full timeout budget instead of remaining background process time
• Bug Fix: Fixed Undefined array key "tables" crash when mysqldump fails and falls back to PHP-based export
• Bug Fix: Fixed error_reporting never being restored on success paths in zip creation and folder backup
• Resilience: Error handler no longer kills the process for fatal errors from external themes/plugins (e.g. WooCommerce dependency in child themes)
• Reliability: Added pre-flight disk space check before DB and folder backups to fail early with a clear message
• Cleanup: Removed dead retry parameter from wp_remote_post calls

2.5.7

• Bug Fix: Fixed fatal error during restore where $presigned_urls (stdClass) was passed to sprintf instead of the directory path string
• Bug Fix: Made mkdir recursive when creating tmp/db/ directory so it succeeds even if the parent tmp/ directory was cleaned up
• Restore Fix: Clear stale background process queues after DB import to prevent source site’s backup tasks from firing on the destination

2.5.6

• Concurrency Fix: Added MySQL advisory locks to prevent concurrent background handlers from processing the same batch simultaneously
• Reliability: Fixed race condition where multiple handlers could duplicate compress, encrypt, and upload operations
• Upload Fallback: Improved upload step to construct expected encrypted file path when step metadata is missing, preventing silent upload skips

2.3.7

• Progress Bar Fix: Resolved progress bar jumping back to 1% during database backup operations
• Memory Management: Implemented dynamic memory management with automatic page sizing based on available system resources
• Error Handling: Added robust validation and error handling for S3 file uploads with proper file path checking
• Logging Improvements: Enhanced logging system with better filtering to prevent progress bar interference from verbose messages
• Debug Tools: Added conditional debug logging (WP_DEBUG only) to help identify unmapped progress messages
• Database Optimization: Improved database export operations with dynamic row increment sizing and better memory monitoring

2.3.6

• Reliability Fix: Disabled async dispatch in favor of direct processing for guaranteed execution on all hosting environments
• Compatibility: Resolved backup hanging issues on AWS and other servers where async HTTP requests may fail silently
• Stability: Reverted to proven direct processing approach for maximum reliability across all hosting providers

2.3.5

• UX Improvement: Disable Backup/Restore buttons when all components are excluded to prevent empty backups
• UX Improvement: Fixed progress bar jump from 1% to 0% at the start of backup/restore operations
• Bug Fix: Added validation to prevent silent failures when attempting to backup with all components excluded

2.3.3

• Bug Fix: Fixed is_processing() method compatibility issue with different WP Background Processing library versions
• Compatibility: Replaced method call with direct transient check for maximum compatibility

2.3.2

• Security Fix: Added nonce verification and capability checks to prevent unauthorized access (CVE-2025-3455)
• Reliability: Simplified background processing for maximum compatibility across all hosting environments
• UX Improvement: Fixed progress bar freeze after restore completion and login
