Forum Error, Fixed Now

[Slim]

Many thanks to David for reporting this. You may have seen the error:

Call to undefined function idna_maps_not_std3()

When attempting to view or start a thread. This was due to a bug (sort of) introduced by SMF 2.1.6.

idna_maps_not_std3() is a function related to the processing and validation of domain names that contain non-ASCII characters. It looks like SMF 2.1.6 has a stricter dependency on this than previous versions.

Critically, the function depends on a package that provides the internationalisation extension for PHP, php7.4-intl in this case. This has been installed now and the problem has been resolved.

A lot more info here if interested, in a post from one of the lead developers on the SMF forum.
