Is the Purge Re: Prefixes option in the dashboard obsolete?

[rich20]

Describe the bug
We have the Purge Prefixes option in the Dashboard -> Tools (see image below). But you cannot remove prefixes with this option.
Message: No message subjects starting with 'Re' were found.
I think that was an option for K3, where every title in an answer started with Re. Now we have ‘Replied by’ and username.

We only have Re-prefixes on the index page and you can disable these prefixes in the configuration (Frontend tab).

I just installed a test version with 6.3.8 and then updated to 6.4.0-RC3.
Then I clicked on the Kunena dashboard/tools “Aw: Remove prefix” field and entered at the top of the Aw: field and clicked Delete prefix. It came the message:
success
The post subject 9728 (starting with 'Aw:') has been changed.
I searched for a long time to find post #9728. The “Aw.” was removed there.
Then I noticed that the “Aw:” was removed in all category posts.

You probably forgot to put a colon after Re (Re:)

A question on the side: is it possible to download the installation files pkg_kunena_v6.4.0-RC3-DEV_2025-01-21.zip and pkg_kunena_languages_v6.4.0-RC3-DEV_2025-01-21.zip again somewhere for test purposes?

I couldn't find anything in the areas I had access to.

With the function “Aw: remove prefix” in the configuration (frontend tab), no “Aw:” can be removed before the titles. It could only prevent “Aw:” from being set before the title. Existing “Aw:” are not removed before the titles.
This makes this menu entry obsolete.

The “Aw: Remove Prefix” in the Dashboard -> Tools makes more sense if you have very old posts and it works.
I tested it with a copy of my Lifesite, where there are posts from the beginning of January 2012 that all have “Aw:” in front of the titles. This goes on until the end of August 2012, after which there are no more “Aw:”.

My suggestion is to remove the entry in the configuration but leave the function in the tools.
There are still many users who are now trying to migrate from Joomla 3 to Joomla 4 or Joomla 5 who, if Kunena is installed, can use this tool.

The ‘Disable Re: in subject’ option in the configuration is useful as it removes the Re on the index page, which is still prefixed.
But if removing it with the tool in the dashboard works for very old posts, then I'll close this ticket.

These versions no longer exist. We update our test versions after each merge to test if a bug fix has produced the desired result. These are only temporary versions, which are constantly being adapted.
