Result:
[CX] Translation initialization failed.
Note this is also a translation which the owner is not able to save. On her side she gets:
TypeError: this.translationView.categoryUI is null
PS: Would be much easier if one would be able to switch to source view and just copy the wikicode. Would at least be able to workaround errors. And also would be able to fix some problems faster (e.g. remove/fix/rename a template etc)
