Thread:Extension talk:VisualEditor/Selecting 'Edit' button produces no observable result.

I am running with MediaWiki 1.25. The Parsoid service is active, and I can demonstrate that it can parse a page at $url/$prefix/$pagename. When I attempt to invoke "Edit," the result is indistinguishable from just viewing a page -- in fact, when I select "Edit Source," then "Edit," I am returned to an uneditable page that shows no apparent difference from simply viewing the page. The generated URL contains "&veaction=edit," so it is trying to invoke Visual Editor. These events do register in the HTTPD access_log, but the error_log is silent.

VisualEditor does in fact appear in Special:Version.

Is it possible that I have made a simple error in configuration? These are pertinent entries (IP address fictionalized to 99.99.99.99):

o LocalSettings.php: require_once "$IP/extensions/VisualEditor/VisualEditor.php"; $wgVisualEditorParsoidURL = 'http://99.99.99.99:8000'; $wgDefaultUserOptions['visualeditor-enable'] = 1; $wgHiddenPrefs[] = 'visualeditor-enable'; $wgVisualEditorParsoidPrefix = 'localhost';

o parsoid/api/localsettings.js: parsoidConfig.setInterwiki( 'localhost', 'http://99.99.99.99/mediawiki/api.php' );

I appreciate any insights that would help me to move further along toward resolution. Thank you!
