Thread:VisualEditor/Feedback/cannot open the specialcharinspector-characterlist-insert page

Using Firefox 39.0, Windows 7, Monobook skin.

A few months ago, I edited MediaWiki:Visualeditor-specialcharinspector-characterlist-insert on Navajo Wikipedia and added some needed characters. Now I’m trying to make an additional minor edit, but I cannot open the page. Every time I try to edit it, I get this error:

Internal error[f693324e] 2015-07-21 19:18:11: Fatal exception of type "MWException"

I’m not sure if I’m doing something wrong or if the page is corrupted somehow.
