So first of all, check what the value of user_touched is for that user in the database. It should be a timestamp. If its a timestamp for some time in the future, that would cause the problem.
If this is not a timestamp, then what this means is that there is a conflict in updating the user object, which would probably indicate a bug in SemanticMediaWiki (or possibly another extension). It could happen if: * Something gets a User object, call it $user1 * something else gets a user object (for same user) call it $user2 * $user2 gets updated (e.g. preference changes, email change, password change) * $user1 gets updates. But MediaWiki detects that the user was updated since user1 was fetched, so it errors Basically what is happening is there is an edit conflict in updated the user's preferences. Which definitely means a bug somewhere, depends what extension is trying to update the user (Which raises the question of why user preferences are being updated at all during rebuildData.php). Which doesn't really answer your question about how to fix, but hopefully leads to the right direction of what's wrong. -- Brian On Mon, Dec 11, 2017 at 7:15 PM, Evans, Richard K.
