Risolvere: Fix Subsite Blog Id Mismatch Import

Fix per Fix Subsite Blog Id Mismatch Import

When you hit subsite blog id mismatch import, start with the Multisite Migrate job log: last completed chunk, PHP/memory messages, HTTP 502/504, disk/inode errors, or cloud auth failures. Multisite archives are larger and table-heavier than single-site jobs, so shared hosts interrupt long PHP requests — Jobs in Chunks exist specifically for that.

Check tmp/disk free space, upload_max_filesize for imports, S3/Drive/Dropbox/SFTP credentials for Plus uploads, and security plugins that block admin-ajax. After restore issues, verify siteurl/home, rewrite rules, domain mapping (sunrise.php), object-cache drop-ins, and CDN caches. Reproduce once on Staging before changing production limits.

Diagnosi dal log per «Subsite Blog Id Mismatch Import»

Separate backup failures from post-restore URL/media/login problems. Capture job percent, last log line, HTTP status, hosting class, and whether a local archive already exists. That evidence decides whether you raise PHP limits, free disk, fix cloud auth, or only re-upload.

For “subsite blog id mismatch import”, avoid restarting from scratch if a chunked job can resume. Lost locks, cleared tmp, or a new job ID are common reasons a progress bar jumps back to 0%.

Fix allineati alla realtà Multisite

Raise PHP time/memory enough for safety, but keep chunked jobs — shared hosts can still kill long workers. Free disk and inodes before large network archives. Allow admin-ajax through WAF or security plugins. On Plus, re-test Drive/Dropbox/S3-compatible/SFTP credentials and quotas.

Free handles core backup/restore; Plus covers BYO cloud; Pro covers remote import, empty-server installer, Staging, and split/extract. Pick the tool that matches the failure — do not upgrade tiers hoping a cloud auth typo will disappear.

Dopo che l’archivio è completo

If the local archive is good, you can restore even when cloud upload failed. Fix destination auth/quota, then re-upload, or restore from local. On Staging, confirm HTTPS, mapping, media, and logins before production.

If mid-restore failed, do not “fix” production DNS first — finish Staging validation and confirm table/prefix expectations.

Retention, cifratura e igiene support

For fix subsite blog id mismatch import, keep enough archive generations to roll back a bad deploy or failed migration. Optional .venc AES-256 encryption on Multisite Migrate archives protects copies at rest when you store offsite on Plus destinations. Document credentials, schedule windows, and who may run Network Admin jobs.

Do not delete the last known-good archive until the new Staging restore drill passes and production looks correct for a full business day.
