This has previously worked fine, any ideas what the issue may be?

Ahhh, I’ve sorted this. Somehow the ‘zip’ PHP extension got disabled - can’t work out how this occurred as I know I did an update to 0.9.35 only last week and didn’t have any problems, and haven’t touched the PHP settings… Strange.

That’s pretty odd. It was disabled in your php.ini file? If it was on a shared hosting environment, perhaps cpanel updated PHP and this value got reset?

Thats what I’m guessing happened, but I haven’t the foggiest just what did it exactly. Oh well, I’ll remember that for next time if I see that error.
