ios: database update error

Josefricar · 2026-01-27T16:36:42+00:00

Dear community, since I have updated to Zotero version 8, an error occurs every time I start Zotero, shuting the whole application down. There is a message:
Zotero.DBConnection.prototype.valueQueryAsync@chrome://zotero/content/xpcom/db.js:755:13

This message appears only in the newest version of Zotero. Before I updated to the latest version, there was a message mentioning database malformation.

Can anyone please help me? Thank you
Josef

(macOS, you mean?)

We'd need to see the whole error. Can you provide a screenshot?

But if you've been getting a message about a corrupted database, you need to fix that.

Again, there's a good chance your database is corrupted if you were getting a message about that before. Are you able to provide a Debug ID for Zotero startup, using the Help → Debug Output Logging → "Restart with Logging Enabled…" option? (You may or may not be able to access the menu for that. If not, there's another way to do this.)

I have copied Zotero.splite file from my backup and everything is working now. Simple. Thanks for helping me!

You should check database integrity of the backup from the Advanced → Files and Folders pane of the Zotero settings.

No mistakes. Thanks again
