- Mark a page for translation while selecting priority languages and ticking the "Prevent translations to languages other than the priority languages" checkbox
- Begin translation into one of these languages, select ("Edit") a translation unit
- click "Add description" to enter documentation text for this translation unit
- after clicking "save documentation", nothing happens.
When trying to create the unit directly at [[Translations:(page name)/n/qqq]], one gets the error message "Translation of this page to this language has been prevented by a translation administrator".
Also, the problem does not occur when the "This does not happen when the "prevent translations..." checkbox is not ticked" - in that case the "save documentation" button works.
