Hello

I tried an upgrade from 2.4.24 to 2.5.3 on a staging site ( https://kigges.hwolf.de/ )

After this the upgrade script was ok, but now all date strings a strange like this:

Forumszeit: %02.%08.%2022, %12:%Aug (Europe/Berlin)
or
Allgemeine Termine - holger, %09.%11.%2018, %13:%Nov […] [*] [○] [x] (Rund um Fußball)

It's with also with the default theme.

This has nothing to do with the theme in itself. The date format is defined in the language file. For gernam language these are the lines 17 and 18 in lang/german.lang.

How I searched for the cause:

In the version 20220529.1 the single entry page uses the key time_format_full to format the time. That does it since ages. But because of the deprecation of the function strftime we moved to the PHP-function date with the first version of the 2.5-branch, which was 20220508.1.

For comparision reasons:

- the code line #1658 in functions.inc.php of version 2.4.24
- the corresponding code line #1677 in functions.inc.php of version 20220508.1 (2.5.0)

While strftime wanted the (german) full date format in the format %A, %d.%m.%Y, %H:%M, the function date wants it as l, d.m.Y, H:i. And that difference tells me, that you forgot to upload the language files (at least) for the new version.

Tschhö, Auge
