I also noticed that some of the search pages are broken (in both), like next or refining the search

This is still not fixed.

I know what the problem is. All but 219 Bianchi newforms in the database have dimension=1 and the CM field correctly set to 0 or a negative discriminant, but there are 219 of dimension 2 for which no-one has determined the correct value of CM. So the website code just needs to take this into account.

I will fix this, and will make further comments on the main repository's issue page.
