Okay, I figured this out myself. The “first” save button is the one I needed; it didn’t work because I didn’t fill in the company name (there is no need as this is a small nonprofit running an online barbershop youth singing contest; no clue was given that that was the problem). The “second” save button shouldn’t be there. On all the tabs in my Settings page, the Misc. Settings are displayed at the bottom as well; thus, there are two Save buttons on each tab. I can’t seem to add a screen shot here, here’s a link to a page that has the screenshot.

The Misc. Settings tab is inserted like this at the bottom of all the tabs in my Settings. If you click the bottommost Save button, things are not saved.
