It occurred to me that I had not restarted apache. I did that, and the forum no longer works. I'm getting this error: Call to undefined function mb_convert_case(). I would have thought that the mb_string module would be what is called, but that's installed, and I'm still getting the error.
Update: It's all working fine now, and phpinfo reports php version 7.2.19. I think the reason it was reporting 5.6.38, was because I had not restarted apache. Once I restarted apache, I discovered some php modules that were missing. After installing those, the forum software is back up and running again.
