After clicking "disable" on the Stripe extension, visiting civi gave me an error 500 and does not make an entry in the error log. But going to Drupal home kicks out the following error message:
Warning: require_once(CRM/Core/Payment/Stripe.php): failed to open stream: No such file or directory in Civi\Payment\System::getByProcessor() (line 59 of /home/ourbase/public_html/prbrc/sites/all/modules/civicrm/Civi/Payment/System.php).
The file it's looking for does exist, BTW.
I've fixed this before (see answer), but I just want to uninstall the extension -- it never for us worked anyway.
