I don't know what sentence where is "your note". Feel free to link to specific edits.

Hi @Aklapper , sorry, I see it as a bug, perhaps only documentation (please check my NOTE here), but seems also a "Wizard bug" on the Mediawiki online installation Wizard: if the install process is not a complete success, it must say "something wrong..." and add a link to the solution.

Hi @Aklapper and @Dinoguy1000

Thanks @Ciencia_Al_Poder . I run but it say "DRY RUN ONLY"... and the Guide (Manual:NamespaceDupes.php) say nothing about "how to really run a bug fix"... I edited the Manual, now the example is with with two options, php namespaceDupes.php --add-prefix="checkMePlease-" --fix that was fine, fixed the bug.

Hi @Ciencia_Al_Poder and @Anomie , I run namespaceDupes but no effect (same error message after it when searching). The SQL shows something (!), how to fix the bug that I induced (as I yet described) by changing namespaces?

Thanks @daniel, it is ok? I submitted as https://phabricator.wikimedia.org/T230747

Hi @daniel , thanks the fast reply (!). Explain context and copy/paste complete dump:

Hi, it is the same problem? It was really solved?

Thanks @TTO , was a fast comment, perhaps the best is to split the problem in two, 1) the "Warnings functionality for the import process" (as T113472); 2) the crash.

Hi , I have big problem, the "no alert", "no notice" (even with --debug) about *namespaces* cause crash in the importation process. The maintenance/importDump.php must show a message to say "hey You need to define namespaces in the LocalSettings.php"
