Thanks for the reply.
I haven't got a clue what version of phpVMS I have, but I downloaded it via the phpVMS link, which is from Github I think, so I assume it's the latest version.
I'm no expert at the php language, although over this last week I've improved :-), but I had a go at your suggestion.
I had a look to see if the entry was already there, but it wasn't, so I added what you said I should (copied and pasted). I wasn't sure where to add it, so placed it at the very bottom of the page.
Unfortunately, it hasn't made any difference, I'm still getting the same error,
Once again, thanks for the help. I'd be lost without it. Any further suggestions/advice would be appreciated.
