We'll check this asap.

@fplanque thx.

What I found out is, that this error only occurs in collections set up with subdomains.
Collections of the same Instance not using subdomains like https://www.genba.org/blogs/sudelbuch/?disp=mediaidx work.
I don't know whether these observations are helpful and not misleading.

I checked. Tables in DB are perfect. The check by maintenance shows no errors.

Regards, Will
