I had Cqrlog working on mint 18.2 then switched to Ubuntu 18.04 bionic beaver to see if I could correct another problem and reloaded Cqrlog and my data just fine. I could not get digital working with fldigi for some reason so went to go back to mint and seemed ok but it won't let me open Cqrlog and the pop up says it can't connect to DB and to put last 20 lines of the err file here. Any ideas what I am missing ? thanks for any help, and feel free to email me direct too. Tom WD0BFO@WD0BFO.COM
