My own sqlitedb maps are not working
I have created about 30 sqlitedb maps 6 years ago, but now they don't work. when I try to add them, it is ending with "unknown error". Last time I used them was half an year ago. I'm using Locus Pro 3.30.2 and still the same phone with the same Android version (Oneplus X, OxygenOS 3.1.4, Android 6.0.1)
I'm also using another sqlitedb map, but that one is working ok, so it NOT like "all sqlitedb files are not working".
One of the problematic map is here (5MB)
Thanks in advance,
