Hello, again, Altrea:
Glad to learn that I've installed the correct native version, not the VM version.
Sorry to learn that you aren't a Mac user. I need someone with that familiarity to guide me. What do you suggest I do to reach Mac users on Apache Friends?
As far as an error log, I found one inside Applications > XAMPP. It's locked and has its last date entered in December, so I don't think that it will be helpful.
When you compare the screenshots I provided, have I installed the correct version number, "7.4.18-0," despite the fact that the file in the Applications folder shows it as v. "1.0.3"? How is that explained?
And, yes, I have MAMP installed in Applications. I installed it four days ago in the event that I get nowhere on correcting the XAMPP problem. Should I delete it now, while there's still hope that I can correct this XAMPP problem?
Warren
