Softaculous install ok?

I’ve spent most of today trying to do a manual install… finally got it, but now the right panel in admin screens says “undefined” and is blank. The left panel (the one that slides out) is also blank.

I had previously played with a copy that had been installed by Softaculous and didn’t notice any issues, but I ran into an issue years ago with another software installed with softaculous. so I always avoid it if I can. But now I am running out of time to get this thing up and running.

Does anyone have experience with installing with softaculous? (I know it can depend on the hosting company, but let’s assume they did everything right…)
