Yes, but it' as simple as all the instances of the 3 letter string "Log" in the code just vanished into thin air.
That line used to be If debugMode then Log(mysqlurl)
This is a B4xpages project, and it seems that most of the botched code was in classes. I do not have much more data since I was so desperate trying to find what happened and when I finally realized the problem fixed it manually. I had online backups of everything from a few months ago, the last time I touched this project.
I have one other important project that I have not yet opened, last edited in the previous B4A version. Will make a zip backup and open it and see what happens. Will do it in a few hours from now.
