Klingt etwas nach dem Problem mit der URL-Umschreibung. Such doch mal hier im Forum nach "MultiViews", das tritt recht häufig auf. Möglicherweise musst du die Option "Kurze URLs" deaktivieren, wodurch sich aber alle URLs im bestehenden Forum ändern.

Was steht denn im Fehlerprotokoll? Was passiert stattdessen, wenn man auf den Speichern-Button klickt? Funktioniert sonst noch irgendwas nicht wie vorher?

Be careful with nofollow. It drops all "karma" coming in from external sites. You wouldn't want to lose that. Just set noindex to not index the post URLs, but keep follow for the link to its own thread that is contained on every post URL page.

Oh, I think named_urls only affects the thread/ URLs, not the direct post links. Those are just shortcuts to a thread with some JavaScript scrolling code to find the post on the page, since there's no traditional hashtag anchor. Maybe post URLs shouldn't appear in a search index anyway and be marked as noindex,follow.

Oh, there is already something in it, it's just disabled by default and not very visible. Could you please look for the configuration option "named_urls" (set it to 1)? I think that was it.

You mean to display the user names with different text colours besides posts and in other lists? No, it's currently not possible. It would also be hard for a plugin because it would require a lot of hooks (which don't exist yet).

Oh, you can use whatever forum (and other) software suits you best.
Is Wordpress in a parent directory (here: the root directory of the domain) or in a parallel subdirectory (here: besides "forum")? If it's in a parent directory, its .htaccess file in the root directory (if present) may interfere here. You'll have to find the offending directives either by comparing both files, or by trial and error. If it's not in a parent directory, I don't see much relevance in it from my limited perspective.

are you sure you are in the right support forum? I see a phpBB installed on your URL.
In case you changed that since, you may want to search this forum for "MultiViews". It gives you a snippet to put in your UNB's main .htaccess file to correct an issue with the Apache web server. There should be a similar comment on that in the file already. Otherwise, you could disable the board's short URLs and not use URL rewriting anymore. It doesn't work everywhere.

Also wenn du diese Übersetzungsteile auskommentierst, wird UNB sie nicht mehr finden und stattdessen den Textschlüssel anzeigen. Das wird eher nicht funktionieren. Du müsstest wenn schon alle Verweise auf diese Texte suchen und deren Verwendung auskommentieren.

Ich sitz grad an nem anderen Rechner und seh den Code nicht, aber du zeigst nur auf eine Sprachdatei. Die kann nur Texte in der Übersetzung ändern und kein Layout oder Daten. Würde mich zumindest wundern. Muss ich später nochmal reinschauen.

Werden nur die alten Daten noch angezeigt oder auch neue weiter gezählt? Mein Vorschlag wirkt nur für die Zukunft. Einer für die Vergangenheit besteht darin, die entsprechenden Werte aus der Datenbank zu löschen.

You mention another point: A guest will not be able to "unlike" a post again. Well, maybe for a short time as long as the page is loaded. But even then, it would be possible for an attacker to delete the +1 counter for any post. Some cookie-based solution might be helpful but that's an entirely parallel user management thing.
