I guess the one thing I can suggest is to try a different browser. This looks a bit like an issue with your privacy settings in your browser.

Sorry, no, I can't debug it based on a screenshot.

Hi! Could you send me a link to your page so I can take a look?

Thanks. It seems that the Zotero API converts those dates into month names. So unfortunately I think sorting by month won't be possible when using Zotero as your data source.

Could you send me a link to your page where you use BibBase?

Thanks for the exemplary bug report. One correction: This only happens "When some works have the same title and authors" and the same year and then searches for itTherefore this really doesn't affect a lot of people. Personally I think it is bad style to publish two different papers using the exact same title in the same year. The above conditions are not the only place where confusion may arise. I think adding a suffix, like "extended version" or "with proofs" or similar is the better practice.

Yes, probably. The default grouping/sort order is by year and any entry that doesn't have a year field will be grouped under undefined.

By the way, 6000 entries is a *lot*! Do you really want your users to look through all that? You might be interested in using filters to provide different views.
