Changelog
1.0.6
Bug Fixes:
- Stop writing
$wpdb->prepare()%placeholder hashes into SQL dumps (Elementorsettings="%7B%7D"/ site-logo fatals). - Exclusive job lock so admin ticks and WP-Cron cannot double-append
filelist.txt. - Heal prepare-placeholder corruption on restore and rewrite absolute URLs in uploads CSS (Elementor google-fonts CORS).
- Remap option/usermeta keys and unknown collations when restoring custom table prefixes.
- Stream large zip downloads with Range support; clear Plugin Check ERROR/WARNING findings.
Features:
- Stronger site-to-site restore: prefix rewrite, serialize-safe URL remap, JSON-escaped URL pairs, and uploads text-file remaps.
1.0.5
Bug Fixes:
- Set WordPress.org Contributors to valid username
fuadkm.
1.0.4
Features:
- Site-to-site restore: automatic table-prefix rewrite and serialize-safe URL remapping when source and destination differ.
- Restore-completed modal with Go to login (sessions are usually reset after DB restore).
Bug Fixes:
- Dump pagination uses
ORDER BYprimary/unique key so large tables do not emit duplicate PKs. - Persist SQL restore offset mid-tick and rewrite
INSERTtoREPLACEso resume cannot fail on Duplicate entry. - Restore ticks survive session wipe via tick token (omit stale REST nonce; clear cookie check when token present).
- Harden staging cleanup and prune missing
active_pluginsafter restore so incomplete plugin copies cannot fatal the site.
1.0.3
Features:
- Import a Stalza backup zip from cloud or another site (Restore Upload backup modal); verified before restore is offered.
- Richer backup progress UI: live scan activity, elapsed time, rotating hints, and clearer phase titles.
1.0.2
Performance:
- Scan phase uses a DFS stack cursor and prunes excluded directories (no O(N²) path re-walk). Mid-upgrade jobs still mid-scan with legacy
resumerestart that scan cleanly. - Admin REST ticks process up to 500 items / 20s (was 100 / 15s); cron job ticks match. Scan phase ignores the item cap and runs under time/memory only so listing finishes in one tick on typical sites.
- Zip STORE for already-compressed media; light DEFLATE for text — less CPU, same zip format.
- Archive seeks
filelist.txtby byte offset (no full reload each tick); scan batch-appends the list. - Admin UI re-ticks ~every 50ms while a job runs (was 1.2s idle gap).
Bug Fixes:
- Scan progress no longer shows a fake ~99% (
N/(N+1)); UI shows files found with an indeterminate bar until archive/dump has a real total.
