Yesterday I activated the Inputbox extension. Today I can't log in into my account:

"There seems to be a problem with your login session; this action has been canceled as a precaution against session hijacking. Go back to the previous page, reload that page and then try again."

I tried deactivating the extension, by deleting "wfLoadExtension( 'InputBox' );" from localsetting.php, but that gave me this error:

"[WiL8XrmwKzsAACaYCMUAAABG] 2017-12-02 19:17:51: Fatal exception of type "Wikimedia\Rdbms\DBQueryError""

What am I supposed to do?

I'm using:

MediaWiki 1.29.1

PHP 5.6.32

MySQL 5.7

This is my website. I don't use caching.

Look up the stacktrace for [WiL8XrmwKzsAACaYCMUAAABG]. See Manual:How to debug

You should enable exception details to be sure what the issue is, but most common cause is you probably need to run update.php
