Ok, I will try.
Does this have anything to do with the migration not working?

Would recommend using an unmodified language pack.

Do you have one in German?

Or should I set everything to English and then try the migration again?

Could you please clarify what version of our software you're converting into and what version of PHP you're running?

Invision Community v4.7.10
PHP v8.1.19

I suspect you're using a non-standard language pack that has an incorrectly translated word (converted_x_of_x)

I use this language pack:

Hello,

I am new to Invision and currently trying to import my users, topics, avatars, etc. from a WCF / WBB 5 forum using the WBB 3 Importer. 

That there can be problems is clear to me - because the version of the importer are not made for WBB 5 forums.

The database connection and the reading of the existing data from the WBB works fine.

But when I start the conversion, this error message appears:

ArgumentCountError: 5 arguments are required, 4 given (0)
#0 /web/applications/convert/sources/Library.php(336): sprintf()
#1 /web/applications/convert/modules/admin/manage/convert.php(559): IPS\convert\_Library->process()
#2 /web/system/Helpers/MultipleRedirect/MultipleRedirect.php(93): IPS\convert\modules\admin\manage\_convert->IPS\convert\modules\admin\manage\{closure}()
#3 /web/applications/convert/modules/admin/manage/convert.php(578): IPS\Helpers\_MultipleRedirect->__construct()
#4 /web/system/Dispatcher/Controller.php(107): IPS\convert\modules\admin\manage\_convert->runStep()
#5 /web/applications/convert/modules/admin/manage/convert.php(45): IPS\Dispatcher\_Controller->execute()
#6 /web/system/Dispatcher/Dispatcher.php(153): IPS\convert\modules\admin\manage\_convert->execute()
#7 /web/admin/index.php(13): IPS\_Dispatcher->run()
#8 {main}

Do you have any idea if I can possibly omit any part of the import, since the error only refers to a part of the import?
