Yes, correct. This is a bug !
We just updated the system to v4.7.3
We are getting an error when we use the new events app.
When we try to use it in English it works, however it doesn't work in other languages.
I said about blank (new, unmodified) language packs provided by Invision Community !
Invision Community automatically assigns English values to empty language packs in language settings. The problem here is not the language pack itself, it's because the localization of language packs other than English is not compatible with the latest update. As @Richard Arch said, it's not configured correctly (date localization error - decimal etc.)
But @Jim M - for some reason - just doesn't accept it and is not focused on problem solving. This problem needs to be directed to the developer team.
We reported this issue via email and @Jim M ignores it even though @Vfrloos also shared the technical details in the first post of this thread.
As a result,
With the last update, Eventes application crashes in languages other than English(US) and languages that use the same DATE localization setting as English(US)!
We request that this problem be taken seriously and forwarded to the developer team.
