Issue in German form

Are you sure you have the locale set right?

Yes. WordPress is set to German and the libriarian user ist set to German too. I made a test with Englich for the librarian user, but I got the German locates. Therefore I guess Iget the German locales. The simple question is: how I need to enter the date? The German variants are:

25.01.2022 (DD.MM.YYYY)
25. Januar 2022 (DD. MMM YYYY)

I will also use the american formats, but these are not works too.

Best regards,

You have to use slashes (/), not periods (.), and three character month names (Jan, Feb, Mar, May, Jun, Jul, Aug, Sep, Oct, Nov, and Dec).

I try it, but got:

Ungültiges Ver?ffentlichungsdatum-Datum (Jan/1/2022): falscher Monat (Jan). Sollte einer von Jan., Feb., M?r., Apr., Mai, Jun., Jul., Aug., Sep., Okt., Nov., Dez. sein.
Ungültiger Typ

Translation:
Invalid publication date-date (Jan/1/2022): wrong month (Jan). Should be one of Jan, Feb, Mar, Apr, May, Jun, Jul, Aug, Sep, Oct, Nov, Dec.
Invalid type

I don’t know what to say. Does it work with just numbers (1/1/2022)? That might work better.

Sorry:

Ungültiges Ver?ffentlichungsdatum-Datum (1/1/2022): falscher Monat (1)

Same message: wrong month

OK, Just a month and year (jan/2022) work on my test install (Linux (CentOS 7), PHP 8.2, WP 6.1.1, English). As does Jan/1/2022.

Question: are you using a MS-Windows server? If so, you might have to use the North American date format (month before day).

Ungültiges Ver?ffentlichungsdatum-Datum (jan/2022)

It doesn’t work.

WordPress 6.1.1 with German locates.

You seem to be using an old (EOL) version of PHP (7.2). I don’t know what is going on.

I change to 7.4, the same issue. I don’t think it’s a problem of the PHP version, but I will install a test WP site with PHP 8.2 and come back in the next days.

Hi,

I install a new WordPress instance with PHP 8.0 and only one Plugin, the WebLibrarian. Now I get more error messages:

Warning: Undefined array key “type” in /var/www/web775/html/web_librarian/wp-content/plugins/weblibrarian/includes/WEBLIB_Collection_Admin.php on line 663

Ungültiges Ver?ffentlichungsdatum-Datum (Jan/2022): falscher Monat (Jan). Sollte einer von Jan., Feb., M?r., Apr., Mai, Jun., Jul., Aug., Sep., Okt., Nov., Dez. sein.
Ungültiger Typ

OK … I switch the whole site to English of my 7.2 instance.

And I can add records at all!!!

I fear your plugin is not compatible with German dates. That a application is running in a development environment is nice, but …
You should remove the german language from the plugin page. If you really want to solve the issue feel free to ask me for testing.

I will stop any activities, because it doesn’t work!

Best regards,
Uwe

I have no control over the German version and don’t specificly support the German version. I have no clue as why it does not work properly.
