While working on the "bad categories/templates" feature we decided to go with an "allow everything by default" mode when no CommonsHelper2-compatible configuration for a local wiki could be found.
With T196969 we enabled the FileExporter extension for a very small subset of wikis. But the FileImporter allows imports from all wikis in the cluster. Users can easily make use of this by manually providing a ?clientUrl=… parameter in the URL, and already did.
- An import from a wiki without a config file is not allowed
- The following error message is shown on our error page:
The file could not be imported. There is no configuration for wiki %s yet. You can create a configuration for the wiki <a href=”…”>here</a>.
