About [[MediaWiki:Articlefeedbackv5-error-abuse/en]]
I know that this extension is currently enabled only on a small set of Wikipedia wikis, but I strongly encourage to think on the possibility to replace all Wikipedia occurrences from this group to {{SITENAME}}. I don't see any reason for not getting this feature enabled on sister projects or even at external wikis.
I suggest you create an issue report in bugzilla: for this. See mw:Bugzilla and mw:How_to_report_a_bug and for a walk through. Please let us know if you require any help.
