Required fields note typo in red text on front-end subscribe page

So, there’s a note in red text at the top of the front-end subscribe page that says:

“All field with labels in red text are required fields.”

The word “field” should be “fields”.

Since I couldn’t find anywhere that’s specified in the phpList back-end, presumably it’s hard-coded in a file somewhere. I’ll fix that here in a bit.

But, I was wondering if there’s a more “permanent” way to fix it (so, somewhere that it won’t be overwritten the next time a new version of phpList comes out)?

Alternatively, is there a way to get it fixed on the developer end of things so that the typo isn’t there for anyone downloading the product?
