This is not related to importing. You should not restart the import for this issue.
The wiki moderation queue entries are not actually placed in the xf_moderation_queue table. They are placed in the vw_ping table, which controls various types of alerts in VaultWiki. The contents of both tables are used when viewing the moderation queue. If you have vw_ping entries with both pingtype = 0 and userid = 0, those are moderation queue entries.
If there are no queue entries in vw_ping:
- If watched content notifications are not sending, this might be a clue to why your moderation queue is not updating, since the processes are similar.
- Are XenForo's error logs empty? If not, please look for entries that mention 'instantmodalert'.
If there are queue entries in vw_ping:
- There are also some add-ons that interfere with wiki entries appearing on the moderation queue. I don't remember the names, but one is a moderation-related add-on. If you have any add-ons like this, try disabling them first to see if it makes a difference.
