The main problem here is you're running development mode which, in turn, enables debug mode. If this is a live site, it shouldn't be running, or it should only be enabled for specific IP addresses or even only for the CLI.

If development mode wasn't running then this deprecation notice wouldn't interrupt the process.

The problem lies with the paradox of trying to support a wide range of PHP versions. We can't support any component in Zend Framework higher than version 2.4.0 because that's when the PHP requirements change beyond PHP 5.4. They didn't add support for PHP 7.2 (which I believe you're running, based on the error) until ZF 2.9.x (I think).

This is fixed in XF 2.1 because we're bumping our minimum to PHP 5.6 which is fine for ZF 2.10.0 and above and therefore we can be surer of a breadth of PHP version support.

You may be able to work around the issue with something like this in src/config.php:

error_reporting(error_reporting() & ~E_DEPRECATED);

This will keep the error reporting level the same, but remove the E_DEPRECATED level.

I'm good with that, thanks Chris. Nice to know its not important, and more aligned with versions. Thanks.

or it should only be enabled for specific IP addresses

Out of curiosity, how is development mode enabled for just an IP in XF2?
