Ok, that's a start. Can you get the rest of the stack trace for the exception so we can figure out how that's getting called?
Sure. How do I get a full stack dump when the error appears only in the Chrome developer console?
BadMethodCallException from line 845 of <...>/w/includes/session/SessionManager.php: Sessions are disabled for this entry point
I've already enabled $wgShowExceptionDetails (which caused slightly more detail to appear, but no stack dump) and set every other debugging flag in sight on https://www.mediawiki.org/wiki/Manual:How_to_debug#PHP_errors in LocalSettings.php and in index.php. The only output I get is the above line in the Chrome developer console. The error does not appear in the associated Apache error log file.

I feel like that sessions error was something we fixed months ago but can't find details right now. Certainly not the first time I've seen it...
