We just updated to the latest wiki and fa-external-link is no longer displaying the icon for external links in the wiki.
I believe when the project was updated for font awesome fa-external-link changed to fa-external-link-alt and needs to be changed below:
django-wiki/src/wiki/plugins/links/mdx/urlize.py
Line 143 in a691267
icon.set("class", "fa fa-external-link")If I'm not mistaken the pro-version of font awesome still has fa-external-link but I'm not sure if there were plans on handling that.
