Unsupported operand types error

[lennyg]

I just upgraded to 1.36.31 from 1.34. When I do:

http://localhost/zm/api/monitors/alarm/ ... nd:on.json

I'm getting:

"Unsupported operand types: string - int"

This was working on the old version. Any thoughts on what's going wrong?
Thanks

Post the actual log, we need to know which line is generating that error.

Did you ONLY upgrade zoneminder? That looks more like a complaint from a newer php to me.

You’re absolutely right. I actually got a new computer, with a whole new installation of Ubuntu.

Which log file should I be looking at? I looked around and couldn’t find anything relevant.

Thanks

Found it.

Line 303 of /usr/share/zoneminder/www/api/app/Controller/MonitorsController.php needs to be:

$status = intval($status) - 1;

That did the trick. Thanks for your help and your quick reply (especially considering I didn't give you much info).
